Fuel cell supply for feeding a cathode area in a fuel cell with an oxygenic medium uses an electrically driven stimulating device with variable stimulating output

摘要

Stimulating output/amount of air for a stimulating device (5) alters so that a maximum level is adjusted for the difference/net current between a current (IFC) generated by fuel cells (1) and a current (IA) picked up by the stimulating device. Current generated by fuel cells is measured, in proportion to which an output value is adjusted for the stimulating output.
