Abstract
The invention relates to a method for testing the leak-tightness of a fuel cell stack comprising the steps of operating the fuel cell stack using defined gas supply rates, a defined modification of at least one gas supply rate, detecting at least one cell or cell group voltage and analysing the variation in time of the at least one cell or cell group voltage.
Claims10
A method for testing the leak-tightness of a fuel cell stack comprising the steps of:
- operating the fuel cell stack using defined gas supply rates,
- defining a modification of at least one gas supply rate,
- detecting at least one cell or cell group voltage, and
- analysing the variation in time of the at least one cell or cell group voltage.
