Problems solved by technology

With the passage of time, the area with large deformation is prone to aging, the first to lose elasticity, and finally the electrodes and plates of the fuel cell stack are unevenly fastened to each area
[0021] 2. The second patented technology requires an air cushion bag, which is inconvenient to make and inflated, and is prone to accidents such as air leakage after inflation

Embodiment

[0049] like Figure 4 As shown, a fuel cell stack pressing device with uniform fastening pressure includes multiple groups of single cells 1 composed of guide plates and proton exchange membrane electrodes, front and rear collector plates 2, and a pressure Evenly eject the jacket 3, the front end plate 4, and the rear end plate 34; the front and rear current collecting motherboards 2 are sandwiched between the two ends of the multiple groups of single cells 1; the one with a uniform pressure ejects the jacket 3 It is generally in the shape of the current guide plate and the rear end plate 34 of the fuel cell stack 1 (this embodiment is close to a square), and a pop-up jacket 3 with uniform pressure is sandwiched between the rear collector motherboard 2 and the rear end plate 34 between (such as Figure 7 As shown), the rear end plate 34 also serves as an outer splint with uniform pressure to eject the jacket 3.

[0050] The front and rear end plates 34 are clamped respective...

Abstract

The hold-down gear includes at least one set of single fuel cell composed of diversion plate and proton exchange membrane electrode, front and back afflux motherboards, even pressed ejectable jacket plate, front and back end plates. The front and back afflux motherboards clamp two ends of at least one set of single fuel cell. The even pressed ejectable jacket plate is between motherboard and end plate. Front and back end plates are positioned at outside motherboards and end plates. At least two pullrods are setup at the front and back end plates. There are fastening screw caps on two ends of the pullrods. Adjusting the fastening screw caps impacts front and back end plates so as to fasten fuel cell pile. Features are even pressure.

Description

technical field [0001] The invention relates to a fuel cell, in particular to an improved compacting device for a fuel cell stack. Background technique [0002] An electrochemical fuel cell is a device that converts hydrogen and oxidants into electrical energy and reaction products. The internal core component of the device is the membrane electrode (Membrane Electrode Assembly, referred to as MEA). The membrane electrode (MEA) is composed of a proton exchange membrane and two porous conductive materials, such as carbon paper, sandwiched between the two sides of the membrane. On the two boundary surfaces of the membrane and the carbon paper, there are even and finely dispersed catalysts for initiating electrochemical reactions, such as metal platinum catalysts. Conductive objects can be used on both sides of the membrane electrode to draw the electrons generated during the electrochemical reaction through an external circuit to form a current loop. [0003] At the anode en...
