In　this　study,　a　two-dimensional,　two-phase,　non-isothermal　and　steady-state　modified　model　of　proton　exchange　membrane　fuel　cells　is　developed.　The　Forchheimer＇s　effect　(Non-Darcy　effect)　is　coupled　in　the　model,　and　its　impact　on　liquid　water　removing　process　in　flow　channels　with　baffles　having　different　shapes　is　discussed.　Simulation　results　show　that　the　liquid　water　is　able　to　be　removed　more　at　the　regions　around　baffles.　At　the　same　time,　the　baffle　shapes　reform　the　liquid　water　distribution.　When　using　the　baffles　having　larger　dimensions　(e.g.　using　rectangular　baffles　or　trapezoidal　baffles),　the　flow　spaces　around　baffles　decrease　more　and　the　liquid　water　is　removed　more　because　of　the　increase　in　local　flow　velocity.　As　a　result,　the　concentration　polarization　is　weakened　and　cell　performance　is　improved　more.　Moreover,　a　streamline　baffled　flow　channel　that　is　designed　for　the　purpose　of　both　increasing　the　cell　performance　and　avoiding　excessive　increase　in　pressure　drops　is　discussed.　Simulation　results　show　that　this　flow　channel　design　can　both　avoid　too　much　increase　in　pressure　drop　and　facilitate　the　liquid　water　removing　out　from　the　fuel　cell.　©　2020　Hydrogen　Energy　Publications　LLC
