Fuel cell system and method

A fuel cell system, comprising:

• a fuel cell having a cathode gas inlet, and an anode gas inlet;
• a sensor configured to monitor a parameter associated with performance of the fuel cell during operation;
• a blower configured to communicate cathode gas to the cathode gas inlet during operation of the fuel cell;
• a second apparatus configured to communicate an anode gas to the anode gas inlet during operation;
• and
• a controller in communication with the sensor, the blower, and the second apparatus so that, when the parameter reaches a predetermined value, the controller sends a signal to the blower that reduces the flow rate of the cathode gas to the cathode gas inlet.
