摘要：
In a process and apparatus for two-stage supercharging of process air for a fuel cell, in one of the two charging stages, supercharging taking place by means of a displacement machine. In the other charging stage, supercharging is performed by means of a combined expansion and compression machine. Energy is recovered from the exhaust gas of a fuel cell by means of the combined expansion and compression machine.
