Abstract：

An　experimental　investigation　of　fuel　cells　performance　under　different　gravity　conditions　has　been　conducted.　An　in　situ　visual　observation　of　two-phase　flow　inside　fuel　cells　in　normal　gravity　and　microgravity　has　been　performed,　respectively,　in　a　drop　tower.　The　effect　of　gravity　on　mass　transfer　in　fuel　cells　was　analyzed　and　discussed.　The　experimental　results　indicated　that　when　the　fuel　cells　operate　at　high　current　density,　its　performance　in　microgravity　is　worse　than　it　in　normal　gravity　condition.　Carbon　dioxide　bubbles　can　not　discharge　in　time　from　the　flow　channels　because　of　disappearance　of　buoyancy　lift　in　microgravity　condition.　It　results　in　a　negative　influence　on　the　mass　transfer　in　direct　methanol　fuel　cells.
