Fuel cell knowledge

The fuel cell consumes hydrogen, and the cost of consumption is the price of hydrogen consumption.

At present, the selling price of hydrogen in commercial hydrogen refueling stations in my country is between 30-120 yuan/kg (Shanghai Yilan hydrogen refueling station hydrogen price is 40-45 yuan/kg), calculated on the basis of a passenger car’s battery life of 100 kilometers per kilogram , And its cost is 30-120 yuan/100 kilometers.

   The cost of fuel cell itself is related to the output. Because foreign fuel cell vehicles are more mature than domestic ones, the cost is relatively low.

  According to calculations based on relevant data, when the output of fuel cells in foreign countries reaches 500,000 units, the cost can be reduced to 40 US dollars/kW. At present, due to the small output in China, the battery cost is between 10,000 and 15,000/kW.

   The infrastructure for fuel cell vehicles is a hydrogen refueling station. The construction cost of a hydrogen refueling station is related to its hydrogen refueling capacity. Generally speaking, the greater the hydrogen refueling capacity, the higher the overall investment price of the hydrogen refueling station.

  According to public information, the investment scale of domestic hydrogen refueling stations with a hydrogen supply capacity of 500kg/d is between 12 and 18 million.

  The cost of Nanhai Ruihui hydrogen refueling station is 15.5 million yuan, the cost of Foluo road hydrogen refueling station is 12.5 million yuan, and the cost of Hanlan Songgang Chantan Road hydrogen refueling station is 29.85 million yuan.

   At present, the highest construction price of hydrogen refueling stations in my country is the Shanghai Yilanjinshan hydrogen refueling station. This hydrogen refueling station is currently the world's largest hydrogen refueling station with a total investment of 55 million yuan.

  2. Hydrogen fuel cell cars and its comparison with electric cars

    a hydrogen car can be taken from empty to full in a few minutes at a fuel pump, conveniently like a petrol or diesel car

    How does a hydrogen fuel cell car work?

    As the driver of a hydrogen car, just like with a petrol or diesel car, you don’t need to know much more than this: you put hydrogen in using a fuel pump at a filling station, which is used as fuel to generate electricity. This electricity is used to power the wheels.

    When you put hydrogen in the car, it’s stored in a secure fuel tank like petrol or diesel is. It’s fed into the fuel cell, which is what generates the electricity. It uses chemistry to combine hydrogen and air (oxygen) and generate electricity. Inside the fuel cell is a liquid with a positively charged anode on one side and a negatively charged cathode on the other, a bit like a battery. In the cell, hydrogen atoms split into protons and electrons – the former turning into the exhaust product (pure water) and the latter providing the power for the car’s electric motor. As with a battery pack, there are lots of smaller reactions happening in the fuel cell

  3. Why Might I Be Interested in a Fuel-Cell Vehicle?

    Typically, a fuel-cell system is twice as efficient as a gasoline system.

    Automotive fuel cells are seen by many as the best bet for widespread replacement of internal combustion engines in the U.S. This is a country where cars and trucks tend to be big. Driving distances also tend to be longer than battery-electric cars can accommodate — or so many motorists think.

    The argument for fuel-cell vehicles is pretty simple: A fuel-cell electric system isn't range-constrained like a battery-electric system. Fuel-cell vehicles aren't tethered to charging cords. They carry enough fuel for 250-350 miles of range and their tanks can be refilled as quickly as that of standard vehicles' gasoline tanks. Few think Fuel-cell vehicles will replace battery-electric cars, which can make a lot of sense for drivers with short commutes. But they are expected to become a significant part of the alternative-fuel fleet in coming years.

    Typically, a fuel-cell system is twice as efficient as a gasoline system. Most of the fuel-cell vehicles coming to market in the n

  4. Is Hydrogen Fuel Battery safe? How is it kept safe?

    Hydrogen is the lightest of the elements. So even though it is highly flammable, escaped hydrogen dissipates quickly.

    The short answer is that hydrogen behaves differently from gasoline. But generally it is about as safe as the gasoline we now put in most vehicles' fuel tanks. In fact, the average gasoline tank holds three to four times the energy — and thus three to four times the explosive power — of the hydrogen tanks that the first fuel-cell electric vehicles will be using.

    Hydrogen is the lightest of the elements, approximately 14 times lighter than air. So even though it is highly flammable, escaped hydrogen (burning or not) dissipates quickly and typically in a narrow column shooting straight up into the atmosphere.

    Its vapors don't pool on the ground, as do gasoline's heavier-than-air vapors. So in most cases, hydrogen doesn't present as great a fire or explosive danger. To further minimize the potential for explosion, almost all hydrogen fuel stations store the gas above the ground in well-vented areas.

  5. Are hydrogen batteries really green?

    Hydrogen is the most abundent chemical element in the universe.

    Hydrogen has been hailed as a carbon-neutral alternative to liquefied natural gas, and hydrogen fuel cells are also being developed as an alternative to traditional lithium batteries.

    Energy efficiency and renewable energy like wind and solar PV – the cornerstones of any clean energy transition – are good places to start. Those industries employ millions of people across their value chains and offer environmentally sustainable ways to create jobs and help revitalise the global economy.

    While lithium has long been touted as the future of advanced batteries, the technology’s limitations and accidents at lithium facilities have encouraged manufacturers to consider alternatives to power the battery revolution.

    Hydrogen is extremely abundant in the atmosphere, making it an attractive alternative to materials with limited supply such as lithium or zinc.

    Hydrogen fuel cells also only produce water and heat as part of the energy production process, presenting an ef

  7. Safe production and utilization of hydrogen energy under the background of carbon neutralization

    Safe production and utilization of hydrogen energy under the background of carbon neutralization

    1、 Hydrogen energy development on double carbon target
    What is carbon neutralization? The concept of carbon neutralization is actually a balance, that is, the carbon emitted by human activities is balanced with the carbon consumed, and carbon dioxide is discharged into the air. What are the ways? We see its importance and urgency. The Paris Agreement in 2015 has raised the problem of carbon neutralization, which controls the global steady temperature rise within 2 degrees before industrialization, and tries to control it within 1.5 degrees. In 2050-2100, the global goal of "carbon neutralization" is achieved, namely, the balance between emission and absorption of greenhouse gases. China will improve its national independent contribution. To reach the peak by 2030 is "carbon peak", and to achieve "carbon neutralization" in 2060. This is China's promise to the world. That is, we do not need to achieve carbon neutralization by 2100 and in 2060, it will reflect the responsibility of a g...

    Current status and prospects of fuel cell development

    Since the 21st century, with the development of science and technology and the gradual improvement of human living standards, the demand for automobiles has also begun to grow rapidly. Automobile exhaust has become one of the main pollution sources of the atmosphere, and traditional internal combustion engine vehicles are difficult to solve the problem of fuel shortage and reducing pollutant emissions.

    Therefore, in order to achieve the goal of energy saving and emission reduction, countries advocate the use of unconventional vehicle fuels as power sources for pure electric vehicles, hybrid vehicles, fuel cell vehicles and other new energy vehicles to reduce or even not emit greenhouse gases to reduce the impact on the atmosphere. Pollution. With the increasing awareness of environmental protection in countries around the world, a consensus has been reached to reduce or reduce greenhouse gas emissions, and many countries and regions have issued relevant policies to control and limit...
