Excessive stack temperature affects the performance of membrane electrodes and their lifetime. Therefore, cooling systems are indispensable in fuel cell systems; cooling systems are generally divided into air-cooled and water-cooled, but Air-cooled systems are too large, especially in high-power fuel cells;
大功率燃料电池选用水冷却系统，但在水冷系统中经常出现水泡，再加水时很难将水泡排尽，随着水温升高会产生部分气泡，随着气泡的运行会聚积成大水泡，大水泡活动性差，容易聚积在一处；在给燃料电池散热时，一旦大水泡出现在水流道时就会出现散热不均匀，会使膜电极局部过热极易被烧坏，降低燃料电池的寿命。High-power fuel cells use water-cooling systems, but blisters often appear in water-cooled systems. When water is added, it is difficult to drain the blisters. As the water temperature rises, some bubbles will form, and as the bubbles run, they will accumulate into large blisters. The large blisters have poor mobility and are easy to accumulate in one place. When the fuel cell is dissipated, once the large blisters appear in the water channel, uneven heat dissipation will occur, which will cause the membrane electrode to be overheated and easily burned out, reducing the life of the fuel cell. .
