MICROSTRUCTURED FLOW FIELDS

摘要

A flow field for an electrochemical cell such as a fuel cell is provided, having micro-flow channels having a width or depth of less than 800 mu m, a pitch of less than 800 mu m, or a proportion of inter-channel land area of less than 25 %. The channels may further comprise micro-features within the channels. A flow field plate comprising the subject flow field is provided.
