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 8):
The method of  claim 5  wherein the initial warming operation heats the stack for an initial time period, the predetermined warming operation heats the stack for a predetermined time period, and the initial time period is greater than the predetermined time period.
