Abstract:
The present invention is directed to an electrochemical fuel cell. The configuration of the fuel cell stack provides a multiple-legged current flow path therethrough. Electrically isolated zones are formed in the cells and one coupled in a serial manner. This configuration provides incremental voltage summing such that additional power converting element are not needed to match the stack output to the load.
