Patent ID: 8377602

Claim:
A method of regulating the temperature of a fuel cell that is cooled by a cooling fluid passing through the cell via a cooling circuit, the method comprising the following steps: measuring a temperature Tsm of the cooling fluid within the cooling circuit at an outlet of the fuel cell; specifying a command flow rate Qc for said cooling fluid in said cooling circuit as a function of said temperature measurement; applying the command flow rate Qc in said cooling circuit; measuring an actual flow rate Qm of the cooling fluid within the cooling circuit; comparing the measured flow rate Qm to the applied command flow rate Qc to determine a difference therebetween; and establishing a command temperature Tec of the cooling fluid in the cooling circuit as a function of the difference between the measured actual flow rate Qm of the cooling fluid within the cooling circuit and the applied command flow rate Qc, to compensate for failure of fuel cell temperature regulation caused by said flow rate difference.
