Abstract：

In　order　to　study　the　relationship　between　heat　transfer　and　mass　transport　in　fuel　cell,　a　micro　thin　film　heat　flux　sensor,　which　can　simultaneously　measure　the　temperature　and　heat　flux　inside　the　fuel　cell,　has　been　designed　and　fabricated.　The　results　show　that　the　self-made　sensor　can　detect　the　transient　temperature　and　heat　flux　on　the　surface　of　membrane　electrode　assembly(MEA)　and　the　sensor　is　slightly　affect　the　performance　of　fuel　cell.　The　simultaneous　measurement　indicates　that　the　dynamic　response　of　temperature　is　slower　than　that　of　heat　flux　during　the　fuel　cell　discharge　process.　The　heat　flux　appears　to　be　constantly　changing　with　respect　to　temperature　because　of　the　variation　of　heat　conductivity　coefficient　of　MEA　and　the　effect　of　methanol　crossover.　©　All　Right　Reserved.
