Problems solved by technology

It can be seen that the positive and negative series lead wires of this integrated fuel cell are on both sides of the stack, and there are a large number of independent stack modules, and the space layout of the lead wires is very unreasonable.

Embodiment Construction

[0024] Such as Figure 2-6 As shown, a method for rationally arranging the lead wires of the positive and negative electrodes of the integrated fuel cell is characterized in that the method includes processing the guide plates in the same group of two stack modules on the left and right sides of the fuel cell to be exactly the same , and make the orientation of the positive and negative poles of each single cell exactly the same, so that the two modules can be directly connected in series through their respective current collecting motherboards; The plate processing is exactly the same, but it is processed as a mirror image with the flow guide plates of the fuel cells in the adjacent group, so that although the orientation and arrangement of the positive and negative electrodes of each single cell in this group are completely consistent, they are consistent with the positive and negative electrodes of the adjacent group. The orientation of the negative electrode is just opposi...

Abstract

The invention discloses a reasonable allocation method of positive and negative electrode lead for integral fuel battery, which comprises the following steps: manufacturing each diversion electrode of two electric-pile modes in the same left and right two sides of fuel battery into the same shape; making each battery anode and cathode possess the same orientation completely; cascading two modes directly through itself affluent motherboard; manufacturing each diversion plate of fuel battery in two adjacent electric pile modes into the same shape; proceeding mirror-image manufacturing for each diversion electrode of fuel battery with adjacent group with opposite direction of positive and negative electrode orientation; realizing positive and negative cascade connection of two adjacent groups of electric pile mode; making the positive and negative electrode lead lie in the same side of whole electric pile; realizing minimum distance on the space connection.

Description

technical field [0001] The invention relates to a fuel cell, in particular to a method for rationally arranging the lead wires of the positive and negative poles of an integrated fuel cell. 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 externa...
