are hydrogen fuel cells energy storage devices why

Fuel Cell Systems | Department of Energy

The fuel cell stack is the heart of a fuel cell power system. It generates electricity in the form of direct current (DC) from electrochemical reactions that take place in the fuel cell. A single fuel cell produces less than 1 V, which is insufficient for most applications. Therefore, individual fuel cells are typically combined in series into ...

20.7: Batteries and Fuel Cells

Although fuel cells are an essentially pollution-free means of obtaining electrical energy, their expense and technological complexity have thus far limited their applications. These space vehicles use a hydrogen/oxygen fuel cell that requires a continuous input of H 2 (g) and O 2 (g), as illustrated in Figure (PageIndex{4}).
