Hydrogen Fuel Cell Generator Efficiency

While the remaining 50 will be dissipated as heat or lost through incomplete oxidation within the cells.

Hydrogen fuel cell generator efficiency.

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. Hydrogen can then be utilized to power a fuel cell stack. If the fuel cell is powered with pure hydrogen it has the potential to be up to 80 percent efficient. That is it converts 80 percent of the energy content of the hydrogen into electrical energy.

One kilogram of hydrogen has almost as much energy as a gallon of diesel fuel but per unit of. This is accomplished by the electric motor and inverter. While the price of a pem fuel cell is similar to that of an equivalent diesel generator the cost of the fuel the systems use is not. 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. This range compares to the typical internal combustion engine of a car which is about 25 energy efficient. 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. Department of energy hydrogen fuel cells are generally between 40 60 energy efficient.

They can refuel in just a few minutes and the fueling experience is almost identical to a gas station. According to the u s. In the case of the hydrogen powered e car the losses are. The typical operating efficiency of a fuel cell running at 0 7 volts is about 50.

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. This means that 50 of the energy content of the hydrogen input is converted into electrical energy.
