Regelsystem mit Brennstoffzellenspannungsrückkopplung

摘要

A method and apparatus according to the present invention controls current that is supplied to a load by a fuel cell stack. A minimum voltage of a plurality of fuel cells in a fuel cell stack is monitored. The current load supplied by the fuel cell stack is increased if the minimum fuel cell voltage value exceeds a first voltage value. The current load supplied by the fuel cell stack is decreased if the minimum fuel cell voltage value is less than a second voltage value. The current load supplied by the fuel cell is maintained if the minimum fuel cell voltage is between the first and second voltage values. The current load is increased and decreased based upon a difference between the minimum fuel cell voltage and the first voltage value.
