Abstract
An illustrative example fuel cell assembly includes at least one cooler and a plurality of fuel cells each having an anode and a cathode. Each of the anodes includes an anode flow plate configured to allow fuel to flow through the anode. The anode flow plates have a respective flow resistance that varies among at least some of the anodes based on a distance between the corresponding anode and the cooler.
Claims20
A fuel cell assembly, comprising:
- at least one cooler;
- and
- a plurality of fuel cells each having an anode and a cathode, each of the anodes including an anode flow plate configured to allow fuel to flow through the anode, the anode flow plates having a respective flow resistance that varies among at least some of the anodes based on a distance between the corresponding anode and the cooler.
A method of operating a fuel cell assembly having a plurality of anodes, the method comprising:
- establishing a first fuel flow resistance through at least a portion of a first one of the anodes;
- and
- establishing a second, different fuel flow resistance through at least a portion of a second one of the anodes based on difference in an expected operating temperature of the second anode and an expected operating temperature of the first anode.
