| 摘要 |
The present invention is concerned with fuel cell stack assemblies, particularly with heat exchanger configurations within fuel cell stack assemblies, configured to enhance system efficiency and/or the speed and rate of warm-up of the fuel cell stack. It achieves this by employing a condenser in fluid communication with fuel cell exhaust gas to recover heat and switching means to switch between condensing water from the exhaust gas and not condensing water from the exhaust gas e.g. by bypassing the condenser or reducing cooling therein. |
