The fuel cell system is controlled solely by switching individual cells or stacks on and off.. Current density matching present demand may be controlled in addition. In this way, electrical and/or thermal loading of the fuel cell system is controlled. An I...

A fuel cell battery consists of a reaction device which is aligned with the stack axis and contacting the cell stack. The reaction device treats liquid fuel by reforming with partial oxidation to form fuel gas containing carbon monoxide and hydrogen gas. A...
