Abstract
Electrical conductive means is used to connect first and second cooling assemblies of a fuel cell stack to thereby establish a short circuit path which bypasses the fuel cells situated between these cooling assemblies
Claims24
A fuel cell stack comprising:
- a plurality of cooling assemblies;
- a number of fuel cells situated between successive of said cooling assemblies;
- and conductive means connecting first and second of said cooling assemblies establishing a short circuit path which electrically bypasses the fuel cells situated between said first and second cooling assemblies.
A method of shorting a fuel cell stack of the type comprising a plurality of cooling assemblies between successive ones of which are situated a number of fuel cells, the method comprising:
- connecting a conductive means to a first cooling assembly;
- and connecting said conductive means to a second cooling assembly;
- whereby a short circuit path is established which electrically bypasses the fuel cells situated between said first and second cooling assemblies.
