Abstract

The inhomogeneity of gas concentration is a key factor which can influence the fuel cell performance. This paper proposed a multi-point gas sampling system which can sample gases in different locations of fuel cell and analyze the concentration distribution. Results prove that the gas concentration of large format fuel cell gradually varies along the channel, and the distribution between channels is also different.
