ABSTRACT:
A gas control and operation method of a fuel cell system for improved water and gas distribution is disclosed. The present invention provides for a mechanization of a fuel cell system that allows control of the anode reactant and anode effluent through the anode portions of the fuel cell system to improve water and gas distribution on the anode side of the fuel cells that increases the voltage stability of the fuel cells.
