Description
本发明涉及燃料电池技术领域，特别是一种用于燃料电池热平衡的热交换系统。The invention relates to the technical field of fuel cells, in particular to a heat exchange system for the heat balance of fuel cells.
目前燃料电池系统燃料使用压缩氢气，国内目前压缩氢气压力能够达到35MPa，为避免高压状态下氢气对膜电极的冲击损耗，氢气经多级减压后，才能够进入燃料电池电堆。The current fuel cell system fuel uses compressed hydrogen. The current domestic pressure of compressed hydrogen can reach 35MPa. In order to avoid the impact loss of hydrogen to the membrane electrode under high pressure, the hydrogen can enter the fuel cell stack after multi-stage decompression.
根据波义耳定律和查理-盖吕萨克定律，一定量气体，体积和压力的乘积与热力学温度成正比，故氢气经减压后温度下降。现有技术压缩后的压缩空气温度过高，进入燃料电池电堆的氢气温度低于进入燃料电池电堆的压缩空气温度，造成燃料电池电堆梯度温差及膜电极两侧梯度温差，膜电极长时间处于梯度温差工作条件下易发生加速老化和破损现场，严重影响了燃料电池的使用寿命。According to Boyle's law and Charlie-Gerussack's law, a certain amount of gas, the product of volume and pressure is proportional to the thermodynamic temperature, so the temperature of hydrogen decreases after decompression. The temperature of the compressed air after compression in the prior art is too high, and the temperature of the hydrogen entering the fuel cell stack is lower than the temperature of the compressed air entering the fuel cell stack, resulting in a gradient temperature difference between the fuel cell stack and the gradient temperature difference between the two sides of the membrane electrode, and the membrane electrode is long Time under the working condition of gradient temperature difference is prone to accelerated aging and damage to the site, which seriously affects the service life of the fuel cell.
