摘要:
将单个直接甲醇燃料电池的固体骨架看成开口系统,燃料电池稳定运行时的热负荷由阳极反应、阴极反应和甲醇直接氧化反应产生的3部分热量组成,利用热力学原理将其计算.在双极板上设置平行的冷却通道,将电池电化学反应产生的热量及时排出,有利于燃料电池的稳定运行.根据燃料电池中燃料、氧化剂的流向和冷却通道内冷却水流向的不同,冷却水和壁面的换热分别在恒热流密度和恒壁温热边界条件下进行.计算了2种情况下冷却通道壁面的温度和换热系数.结果表明,前者的换热效果要比后者好,但是,后者保证了工作层面具有恒定的温度,更有利于直接甲醇燃料电池的稳定运行.
Abstract:
The single direct methanol fuel cell(DMFC)is regarded as an open system. The heat loads in DMFC are composed of the ones generated by the reactions in anode and cathode and direct-oxidation.They are calculated based on the thermodynamical principle. Removal of reactive heat in direct methanol fuel cell is favorable to operate fuel cell effectively and safely.According to the flowing directions of the fuel and cooling water, two different cooling boundary conditions are discussed and calculated. The results show that the cooling passage under a constant wall temperature boundary condition is better than that of a constant heat flux boundary condition,and it is preferable to use in the cooling of DMFC.
