Abstract:
Improved methods are disclosed for shutting down and storing a fuel cell system, particularly for below freezing temperature conditions. The methods comprise stopping power production from the fuel cell stack, monitoring its temperature, and repeatedly performing a predetermined warming operation if the stack temperature falls to a normal threshold temperature. In the improved methods, either an initial threshold temperature and/or an initial warming operation are used that differ from the respective normal threshold temperature and the predetermined warming operation.

Claim (Index 10):
The method of  claim 1  wherein the steps of performing the initial and the predetermined warming operations are selected from the group consisting of producing power from the fuel cell stack and heating the fuel cell stack with an electric heater.
