Abstract

The present disclosure relates to a bipolar plate structure usable for a fuel cell, comprising: a substrate having an open flow field for a fluid thereon, the open flow field comprising a plurality offlow regions for the fluid; a plurality of protrusions disposed on the substrate and forming at least one of the plurality of flow regions, wherein the plurality of protrusions have different flow resistances in a first direction and a second direction, and the first direction is perpendicular to the second direction. Through the bipolar plate structure disclosed in the embodiment of the invention, the reaction efficiency and the reaction uniformity of the fuel cell can be effectively improved, and the power density of an electric pile is improved.

Description

technical field [0001] The present disclosure relates to the technical field of fuel cells, and in particular to a bipolar plate structure applicable to fuel cells, a fuel cell including the bipolar plate structure, and a fuel cell vehicle. Background technique [0002] The fuel cell uses hydrogen as fuel, does not need to go through the combustion process, and directly converts the chemical energy in the fuel and oxidant into electrical energy in the form of electrochemical reaction, without going through the heat engine process, so it is not limited by the Carnot cycle. The actual energy The conversion efficiency is as high as 50% to 80%, so it is a high-efficiency energy conversion power generation device. Proton exchange membrane fuel cells are the fifth generation of fuel cells, developed after alkaline fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells and solid oxide fuel cells, which have several advantages, including operating temperature Low, shor...
