Basic Components in a Fuel Cell:
Fuel Cell Stack:
The fuel cell stack in this energy system generates electricity in the form of DC or direct current from the electro-chemical reaction. A single fuel cell produces approximately 1V, which is not sufficient to operate any electrical equipment. Therefore, individual fuel cells are combined to form a stack of the fuel cell. Typically a fuel cell stack may contain more than hundreds of fuel cells.
The fuel processor converts fuel into a form usable by the fuel cell. Primarily, a fuel processor is a type of chemical reactor that converts a commonly available fuel, such as gasoline, methanol, or natural gas, into a gas stream containing primarily the compound(s) required by the fuel cell such as hydrogen (H2) or methane (CH4).
Power conditioning include controlling voltage, current, frequency, and another important characteristic of the electrical current to meet the needs of the application. Fuel cells generate direct current. Here power conditioners use to handle the conditioning of direct current.
Fuel cells are unique in terms of the variety of their potential applications. They can use a wide range of fuels and feedstocks and can produce power for the system as large as a utility power station and small as a computer system. In the upcoming days improved model of the fuel cell will replace household inverters for power generation. Fuel cells are also being used with superconducting coils in space sectors.
