Abstract

A four-cell air-breathing micro direct methanol fuel cell (μDMFC) stack with two double-side patterned PDMS distributors was designed, fabricated, and tested in this paper. A novel n-inlet and n-outlet (NINO) smooth parallel flow field was first introduced. Based on the NINO smooth parallel flow field, the other three kinds of parallel flow field: square protrusion parallel flow field, semicircle protrusion parallel flow field, and triangle protrusion parallel flow field were proposed. Both the results of the stimulation and the test show that the square protrusion parallel flow field plate has the best performance.
