FUEL CELL

摘要

A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first and second metal plates. The coolant flow field is connected to inlet buffers and outlet buffers. Protrusions for limiting the flow of a coolant are provided at the inlet buffers and the outlet buffers on upper and lower opposite end positions of the coolant flow field.
