The use of stainless steel as replacement for graphite in polymer-electrolyte-membrane fuel cells (PEMFCs) has been reported [1], with little difference in performance and corrosion of stainless steel even after prolonged testing of the PEMFC stacks. Therefore, for stationary applications where stack weight is not as critical as for transportation, the ruggedness of stainless steel, as well as its low-cost relative to graphite, make it an attractive material for practical use. To our knowledge, similar studies on solid polymer electrolyte direct methanol fuel cell (SPE-DMFC) stacks with stainless steel flow-dis-tributors are lacking in the literature. As a part of our ongoing research [2, 3] on direct methanol fuel cells, this communication reports the performance of a 5W liquid-feed stainless steel SPE-DMFC. |
