Performance of DMFC with SS 316 bipolar/end plates

摘要: This work mainly emphasizes the development of new materials and design for a bipolar/end plate in direct methanol fuel cell (DMFC). According to DOE requirements, preliminary studies show that SS 316 (Stainless Steel 316) is suitable candidate. Several flow field designs were studied modified serpentine was proposed. end plates fabricated with an intricate on it. The performance single stack DMFC different operational parameters. A long-term test carried out 100 h recycling contaminants MEA characterized. efficiency found be 51% polarization losses are discussed. low permeability resulted increased pressure drop across field, which performance. use as bipolar material will reduce machining cost well volume stack.
