First Claim
Patent Images
1. A fuel cell system comprising:
- a fuel cell unit with at least one fuel cell;
a gas generation system, for supplying the fuel cell unit with hydrogen from an operating medium;
a condensate separator for recovering water from an exhaust gas of said fuel cell; and
at least one ion exchanger unit for removing ions from water;
wherein the at least one ion exchanger unit is arranged in a flow path for the operating medium, between the condensate separator and the gas generation system; and
the at least one ion exchanger is acted on by a mixture of water and the operating medium.
