STARTUP AND SHUTDOWN PROCEDURES FOR OPERATING A FUEL CELL ASSEMBLY |
摘要 |
A fuel cell assembly (20) has an extended operational life, in part, because of unique startup and shutdown procedures used for operating the fuel cell assembly. In disclosed examples, a purge gas mixture of hydrogen and nitrogen includes less than 2% hydrogen for selectively purging portions of the assembly during a startup or shutdown procedure. In a disclosed example, the hydrogen-nitrogen mixture contains less than 0.1% hydrogen. |
