摘要：

Visualization　study　of　two-phase　flow　in　anode　interdigital　flow　bed　of　a　liquid-fed　direct　methanol　fuel　cell　(DMFC)　was　performed　in　a　experimental　system.　A　self-made　DMFC　consisted　of　a　Nafion　117　membrane　electrode　assembly,　a　gold-plated　stainless　steel　cathode　polar　plate　and　a　polycarbonate　anode　flow　field　plate,　which　forms　a　transparent　window　for　observation.　The　inlet　and　outlet　manifold　were　horizontal　in　all　experiments.　Meanwhile,　the　inlet　and　outlet　flow　channels　were　vertical.　The　experimental　results　indicated　that　the　typical　flow　pattern　in　outlet　channels　was　bubbly　flow　and　in　outlet　manifold　was　slug　flow.　Gas　slugs　and　gas　columns　in　the　inlet　channels　lead　to　block　of　mass　transfer　in　the　anode.
