Abstract

The invention relates to the combination cell structural design which is sealed by the fuel cell metal pole plate and the membrane electrode module, concretely is a fuel cell cellular structure and its pile assembly, which includes the mold pressing metal pole plate which has two pieces flow field and the membrane electrode module (MEA). The fuel cell pole plate seals MEA and the seal structure in together and combines the orientation slot and the inspect slot to form the fuel cell unit. The structure formed the only unit module of the generate electric element when groups the pile, reduced the component quantity of the pile assembly, enhanced the assembly speed and the size stability of the pile, and reduced the replacement damage of MEA when assembles, is advantageous in enhances battery's performance, suits the mechanized production of the pole plate and the pile assembly.

Description

technical field

[0001] The invention relates to the combined unit structure design of fuel cell metal pole plate and membrane electrode assembly packaging, in particular to a fuel cell unit structure and stack assembly thereof, which is suitable for hydrogen proton membrane fuel cells. Background technique

[0002] Each battery cell of the fuel cell is composed of a cathode and anode plate with a flow field and a membrane electrode assembly (MEA) in the middle, and has a cooling structure. Taking the hydrogen proton membrane fuel cell as an example, in terms of the design of the anode plate and the cathode plate, the two plates are generally designed as a back-to-back structure, and a coolant flow field is formed in the middle to form a bipolar plate structure, and then connected with the MEA and the sealing line and other components are stacked alternately to form a stack of multiple cells. There is also an electric stack in which the MEA is fabricated on the outside of th...
