Abstract
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.
Claims26
A gas flow control assembly for use in a fuel cell system, comprising:
- an airflow control assembly adapted to adjust flow of air to a cathode side of said fuel cell system based on content variations in an anode exhaust gas leaving an anode side of said fuel cell system;
- and a fuel flow control assembly adapted to control flow of fuel to said anode side of said fuel cell system based on adjustment to said airflow by said airflow control assembly.
A fuel cell system for use with an air supply and a fuel supply, said fuel cell system comprising:
- a fuel cell including an anode side and a cathode side;
- a fuel inlet for receiving fuel from fuel supply for supply to said anode side;
- an air inlet for receiving air from said air supply for supply of oxidant gas to cathode side;
- a gas flow control assembly including an airflow control assembly for adjusting airflow of the air from said air inlet and a fuel flow control assembly for controlling fuel flow of fuel from said fuel inlet,
- wherein said fuel flow control assembly controls said fuel flow based on adjustments to said airflow by said airflow control assembly.
