Temperature regulation of fuel cell systems

摘要

The device has cooling channels (3) attached at a point of a gas stream in an area of a composite material of a fuel cell (2) for receiving a part of incoming process heat from heat radiations and maintaining temperature at a uniform level in an entire flow area of the composite material. The gas stream provides necessary oxidizing agent for an electrochemical reaction and cools the composite material, and the cooling channels heat the composite material at a predetermined phase during operation of the device.
