摘　　要：为了提升聚合物电解质膜燃料电池堆散热性能,文章提出了将一种超薄均温板作为目标电池堆散热结构。基于理论计算和试验验证方法搭建了基于均温板的氢燃料电池堆计算模型,并探究了均温板蒸发段换热系数以及布置角度对目标电池堆散热性能影响。研究结果表明,目标电池堆平均温度和温度均匀性指数随均温板冷凝段对流换热系数增大而降低;水平布置角度下电池堆平均温度和温度均匀性表现最佳,而反重力布置角度表现最差;随着负载的增大,目标电池堆平均温度最高值不超过341.15 K,温度均匀性指数低于1.1,最大温差为4.1 K,使用超薄均温板可使目标电池堆有效散热且具有较好温度分布。An ultra-thin homogeneous temperature plate was proposed as the target heat dissipation structure to improve the heat dissipation performance of a polymer electrolyte membrane fuel cell reactor.The calculation model of a hydrogen fuel cell reactor based on the uniform temperature plate was established using the theoretical calculation and experimental verification methods and explored the influence of the heat transfer coefficient of the evaporation section of the uniform temperature plate and the arrangement angle on the heat dissipation performance of the target battery reactor.The results showed that the average temperature and the temperature uniformity index of the target cell stack decrease with the increase of the convective heat transfer coefficient in the condensation section of the temperature homogenizer.The average temperature and temperature uniformity of the battery stack are better than those of the anti-gravity arrangement at gravity and horizontal arrangement angles.With an increase in load,the maximum average temperature of the target battery stack should not exceed 341.15 K,the temperature uniformity index must be less than 1.1,and the maximum temperature difference must be 4.1 K.The ultra-thin temperature equalizing plate can effectively dissipate heat from the target battery stack and has excellent temperature distribution.
