摘要：

The　effect　of　flow　bed　design　on　the　performance　of　a　liquid　feed　direct　methanol　fuel　cell　was　studied　experimentally.　The　flow　beds　were　designed　and　manufactured　with　different　channel　densities,　channel　depths,　and　ridge　widths.　The　flow　beds　were　machined　on　stainless　steel　polar　plates.　The　experimental　results　showed　that　ridge　width　affects　the　slope　of　the　ohmic　polarization　curve.　A　ridge　width　of　3.30　mm　provided　the　highest　peak　power.　When　the　contact　surface　area　between　the　flow　bed　and　electrode　was　con-stant,　the　effect　of　channel　density　on　cell　performance　was　minimal,　under　the　experimental　conditions　of　this　paper.　The　channel　depth　had　a　considerable　influence　on　cell　performance　with　a　2　mm　deep　channel　achieving　the　best　performance.　The　mechanism　of　the　experimental　phenomena　was　analyzed　in　this　paper.
