Reaction gas temperature and humidity regulating module for fuel cell stack

摘要

A device (2) for regulating temperature and humidity of a reaction gas to be supplied to a fuel cell stack includes a temperature regulation section (4) provided with a first gas guide board (42) through which the reaction gas flows, a coolant guide board (44) through which a coolant from the fuel cell stack flows and a first partition interposed between the first gas guide board and the coolant guide board for exchange of heat between the reaction gas and the coolant and a humidity regulation section (5) coupled to the temperature regulation section with a second partition therebetween and comprised of a second gas guide board (52) through which the temperature-regulated gas flows and a fluid guide board (54) through which a fluid from the fuel cell stack and rich of water contents flows and a humidity exchange film (43) interposed between the second gas guide board and fluid guide board to allow for exchange of water contents between the temperature-regulated gas and the fluid.
