The　two-phase　flow　behaviors　in　a　proton　exchange　membrane　fuel　cell　with　orientated-type　flow　channels　are　monitored　through　the　side-view　direction,　and　the　changing　behaviors　of　cell　performance,　as　well　as　the　temperature　are　recorded　simultaneously　in　the　present　work.　Moreover,　the　mutual　effects　among　cell　performance,　liquid　water　movement,　as　well　as　the　temperature　changing　are　discussed　accordingly.　The　results　reveal　that　the　extra　heating　device　is　always　necessary　during　the　fuel　cell　operating,　while　its　launching　or　not　depends　on　the　immediate　current　situation　and　the　operation　temperature　situation,　where　the　time　duration　without　needing　heating　is　prolonged　from　8　to　115　s.　The　orientational　flow　channel　structure　facilitates　removing　the　liquid　droplets　appearing　in　channel　regions,　and　it　also　enhances　the　convective　heat　transfer,　which　probably　decreases　the　temperature　at　membrane　electrode　assembly　regions　and　slightly　reduces　the　electrochemical　reaction　rates.　However,　the　performance　enhancement　caused　by　orientated-type　channels　is　higher　than　performance　decrease　caused　by　that.　The　observation　through　side　view　on　liquid　water　movement　in　orientated-type　channels,　the　simultaneous　measurements　on　temperature　changing　behaviors　and　the　current　generation　processes　conducted　in　the　present　study　facilitate　better　understanding　the　two-phase　and　heat　transfer　characteristics　in　fuel　cells　with　orientated-type　flow　channels.
