Problems solved by technology

For different plate structures, the fluid inlet and outlet area of ​​the plate will also be different. At present, the structure of the fluid inlet and outlet area commonly used in metal plates is "layer jump", which takes up a lot of space and is not conducive to the plate. Increase in effective area ratio

Abstract

The invention relates to the technical field of fuel cell manufacturing, in particular to a bipolar plate fluid inlet and outlet area, a bipolar plate and a fuel cell. The bipolar plate fluid inlet and outlet area comprises a first monopolar plate and a second monopolar plate which are arranged in an attached mode. A first cavity, a middle cavity, a flow channel cavity and a second cavity are formed between the first monopole plate and the second monopole plate. The first cavity, the middle cavity, the flow channel cavity and the second cavity are sequentially communicated. According to the bipolar plate fluid inlet and outlet area, fluid can directly flow into a distribution area of a polar plate flow field in the inlet area and directly flow out of the distribution area of the polar plate flow field in the outlet area, overturning is not needed, the flowing path of the fluid is shorter, the pressure loss is smaller, and the proportion of the effective area of the bipolar plate is increased.

Description

technical field [0001] The invention relates to the technical field of fuel cell manufacturing, in particular to a bipolar plate fluid inlet and outlet area, a bipolar plate and a fuel cell. Background technique [0002] A fuel cell is a power generating device that converts chemical energy in fuel directly into electrical energy. Because it is an electrochemical reaction, without combustion, and not limited by the "Carnot cycle", the energy conversion efficiency is much higher than that of ordinary heat engines. In addition, fuel cells also have the advantages of no pollution, low noise, and high reliability, and have very broad market prospects in the fields of transportation, stationary power generation, and portable power generation. [0003] The bipolar plate is a key component of the fuel cell stack. Its main functions are to separate the reaction gas, conduct the reaction gas and cooling liquid, collect and conduct current, and support the membrane electrode. Due to...
