Abstract

A device which ensure functionality of a vehicle fuel cell system, even at temperatures of below freezing point, includes at least one heating element arranged in the area of the condensate trap of the fuel cell in such a way that any ice present is heated locally. As a result, one or more melted channels form, through which water may flow after only a very short thawing process.

Claims

1. Apparatus for heating a component of a fuel cell system, said apparatus comprising:

at least one electrical heating element for liquefying ice that is present in said component;

wherein said at least one electrical heating element is arranged locally within said component in such a way that, upon heating, a localized melted water channel forms in ice present in proximity to said at least one electrical heating element within said component.

2. The apparatus according to claim 1, wherein:

said at least one electrical heating element comprises heat-conducting elements in the form of metallic fins; and

said metallic fins extend in parallel within said component, such that a melted water channel forms therebetween upon heating.

3. The apparatus according to claim 1, wherein a plurality of local electrical heating elements, with respective different heating powers, are arranged in different areas of said component.

4. The apparatus according to claim 1, wherein said electrical heating elements are combined into functional groups for heating different components of the fuel cell system.
