Abstract
A temperature regulating system for a fuel cell powered electric motor vehicle assists in maintaining the temperature of the fuel cell stack within a temperature range that provides satisfactory fuel cell performance.
Claims34
A temperature regulating system for an electric motor vehicle, the system comprising:
- (a) an electric motor for propelling the vehicle;
- (b) a fuel cell stack for supplying electrical power to the electric motor, the fuel cell stack having at least one coolant inlet port and at least one coolant outlet port;
- (c) at least one conduit external to the fuel cell stack defining a coolant path for carrying a cooling medium from the at least one coolant outlet port to the at least one coolant inlet port of the fuel cell stack;
- (d) a resistor in thermal communication with the cooling medium for heating the cooling medium, the resistor connected to at least one source of electrical power,
- wherein the at least one source of electrical power comprises regenerative electrical power derived from braking of the vehicle such that the regenerative electrical power thermally regulates the fuel cell stack.
