Hydrogen Fuel Cell Generator Efficiency

Fuel cell cars are very similar to traditional gasoline powered cars.

Hydrogen fuel cell generator efficiency.

Hydrogen fuel cell vehicles which use electric motors are much more energy efficient and use 40 60 percent of the fuel s energy corresponding to more than a 50 reduction in fuel consumption compared to a conventional vehicle with a gasoline internal combustion engine. Hydrogen can then be utilized to power a fuel cell stack. Similar to today s gasoline vehicles fuel cell electric cars can have a driving range of more than 300 miles on one tank of hydrogen fuel.

For a comparable price pem fuel cells can deliver the same generating capacity as diesel generators. They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. This is accomplished by the electric motor and inverter. That is it converts 80 percent of the energy content of the hydrogen into electrical energy.

This means that 50 of the energy content of the hydrogen input is converted into electrical energy. In the case of the hydrogen powered e car the losses are.

This range compares to the typical internal combustion engine of a car which is about 25 energy efficient.

While the remaining 50 will be dissipated as heat or lost through incomplete oxidation within the cells. According to the u s. The electrolyzer s membrane and catalysts work to take advantage of an electrochemical reaction in order to separate the oxygen and hydrogen molecules of water. However we still need to convert the electrical energy into mechanical work.

If the fuel cell is powered with pure hydrogen it has the potential to be up to 80 percent efficient. One kilogram of hydrogen has almost as much energy as a gallon of diesel fuel but per unit of. Our industry grade electrolyzers are a safe and efficient way to produce hydrogen for fuel cell applications. The hydrogen fuel cell requires 2 3 times more energy to drive the same distance as the overall well to wheel efficiency is from 25 35.
