Fuel cell system, especially for vehicle, has fuel cell exhaust gas water recovery device with heat exchanger for achieving heat transfer between 2 different temperature cell exhaust gas flows

摘要

The fuel cell system has a fuel cell exhaust gas water recovery device (12) with a fuel cell exhaust gas heat exchanger (14) for achieving heat transfer between two fuel cell exhaust gas flows (16,18) at different temperatures and a second fuel cell exhaust gas heat exchanger (20) for heat transfer between a fuel cell exhaust gas flow and a coolant (24).
