Abstract

The invention discloses a flow field plate of a fuel cell. The flow field plate comprises a base plate which is equipped with a plurality of flow field channels; one end of the base plate is stuck to a cell polar plate; the flow field channels are arranged in parallel and are through grooves which are formed on the base plate; the parts between adjacent flow field channels are flow field frameworks; arc transition parts are arranged at the ends of the flow field frameworks which are stuck to the cell polar plate and extrude towards the interior of the flow field channels; chamfers are arranged at the ends of the flow field frameworks which are far away from the cell polar plate; the flow field frameworks are provided with a contact face which is stuck to the cell polar plate and an exposed face which is contacted with fluid; and the exposed face is covered with a hydrophobic layer. The invention discloses a fuel cell which comprises a proton exchange membrane, a cell positive plate and a cell negative plate which are arranged at two sides of the proton exchange membrane respectively, flow field plates and cell clamping plates. Each polar plate is connected a flow field plate and each flow field plate is connected with a cell clamping plate. The flow field plate and the fuel cell disclosed by the invention have the advantage of being capable of draining water in time in reaction.

Description

technical field [0001] The invention belongs to the field of fuel cells, in particular to a fuel cell flow field plate and a fuel cell using the flow field plate. Background technique [0002] A fuel cell is a device that directly converts chemical energy in fuel into electrical energy. The battery flow field plate is an important part of the fuel cell, which mainly plays the role of distributing fluid, conducting electricity and supporting the battery structure. Chinese Patent No. ZL200810163683.7 (CN101459246A) discloses a vein-shaped fuel cell flow field plate, which includes two combined flow field plates. There is a roughly square flow field area on the process plate, and the periphery of the flow field area is sealed. Gasket, the main vein for liquid inflow extends along the diagonal of the square, the confluence vein for liquid outflow is parallel to the side of the square, and perpendicular to the outlet of the liquid, one end of each branch is connected to the main...
