GAS FLOW CONTROL ASSEMBLY FOR USE WITH FUEL CELL SYSTEMS OPERATING ON FUELS WITH VARYING FUEL COMPOSITION

摘要

A gas flow control assembly for use in a fuel cell system comprising an airflow control assembly for adjusting flow of air to a cathode side of the fuel cell system based on content variations in an exhaust gas leaving an anode side of the system and a fuel flow control assembly for controlling flow of fuel to the anode side based on adjustment to the airflow by the airflow control assembly.
