Title:
FUEL CELL AIR FLOW REGULATION METHOD
Document Type and Number:
WIPO Patent Application WO2004032268
Kind Code:
A3
Abstract:
The invention relates to a method of regulating the air flow entering the cathode (16) of a fuel cell (12) which is disposed on board a motor vehicle, of the type in which the cathode (16) comprises an air supply line (36) and an air exhaust line (58) and in which the supply line (36) comprises a controlled intake air flow regulation device (32). The invention is characterised in that it comprises the following steps, namely: a step (E1) consisting in measuring the difference (Omes) in oxygen concentration (O2) between a reference gas and the air circulating in the exhaust line (58), a step (E2) consisting in calculating the difference (Omes Oref) between the measured value (Omes) and a reference value (Oref), a step (E3) consisting in determining an optimal intake air flow according to the result of the calculation (Omes Oref), and a final step (E4) consisting controlling the above-mentioned regulation element (32) in order to produce the optimal air flow.
