1. A fuel cell power system comprising:

  • a housing;

    a fuel cell supported by the housing, configured to convert chemical energy into electrical energy to be selectively supplied to a load;

    an air passage in the housing configured to move air relative to the fuel cell;

    means for adjusting mass/energy flow through the air passage;

    a sensor configured to sense a parameter of the fuel cell; and

    a controller coupled to the current sensor to monitor current flow from the fuel cell to the load and to control mass/energy flow adjusting means in response to the sensed parameter.
