Abstract
A compression device for compression of an oxidant for a fuel cell stack includes an oxidant compressor for compressing the oxidant, and an oxidant cooler for cooling the compressed oxidant. The oxidant compressor and the oxidant cooling device are connected to a common coolant circuit.
Claims17
An oxidant compression device for compressing an oxidant for a fuel cell stack, said oxidant compression device comprising:
- an oxidant compressor for the compressing of the oxidant;
- and
- an oxidant cooler for cooling compressed oxidant;
- a common coolant circuit for said oxidant compressor and said oxidant cooler, said common coolant circuit having a coolant that flows through and cools both said oxidant compressor and said oxidant cooler.
1 more element
A method for compressing an oxidant gas that is supplied as a reactant of a fuel cell system, said method comprising:
- an oxidant compressor compresses said oxidant gas;
- an oxidant cooler cooling compressed oxidant gas from said compressor;
- and
- cooling both said oxidant compressor and said oxidant cooler by a flow of coolant in a common coolant circuit.
