METHOD AND APPARATUS FOR MONITORING EQUIVALENT SERIES RESISTANCE AND FOR SHUNTING A FUEL CELL

摘要

A fuel cell power system (10) comprising a fuel cell (14) having a cathode and an anode adapted to be coupled to a fuel supply (17), and which is configured to produce electrical power having a current and voltage output; a controller (30) electrically coupled with the fuel cell (14), and configured to selectively short the anode to the cathode of the fuel cell; and circuitry configured to measure resistance of the fuel cell (14) in time relation to the shorting.
