Technical Examples

A single pump fuel cell system is provided that has multiple valves that have selective positioning to control fluidic flow throughout a fuel cell system. One of the valves provides for high and low concentration fuel dosing. Another valve or series of valves controls an unreacted fuel recirculation loop leading from the fuel cell. Another valve or series of valves control condensate collection by the fuel cell system, and allows the purging of the anode recirculation loop. Each of the valves is selectable between various positions to place the fuel cell system in a desired operating mode. A heat exchanger may also be employed to dissipate heat as desired out of the fuel cell system. A concentration sensor can also be employed to aid in achieving a desired fuel concentration within the fuel cell system.
