Beschreibung
Zusammenfassung:	The invention relates to a novel bipolar plate of proton exchange membrane fuel cell, which is composed of five layers of structure. The middle layer is a water-flow field plate made of a flexible graphite plate with medium density and a water chamber frame made of a laminated resin plate arranged at the periphery of the water-flow field plate; two sides of the water-flow field plate are two pieces of flexible graphite thin flat plate with high density; the sides of the two pieces of high-density flexible graphite thin flat plate against the water-flow field plate are respectively a hydrogen-flow filed plate and an oxygen-flow field plate made of the medium density-flexible graphite plate. The novel bipolar plate of proton exchange membrane fuel cell of the invention has the advantages that: the flow field plate and the electrode plate are separately arranged, which facilitates the production, the structure of the flow field is easier to change according to different conditions; meanwhile, when the high-densi
