摘要
为了研究不同进气温度对质子交换膜燃料电池性能的影响.首先分析了质子交换膜燃料电池反应的基本原理;其次建立了一个质子交换膜燃料电池性能测试平台,通过控制空气和氢气侧压力为0.1 MPa、燃料电池工作温度为60℃时,同时改变阴极和阳极侧进气温度来对一个由十片单电池组成的电堆进行实验.实验结果表明:质子交换膜燃料电池性能受进气温度影响较大,在燃料电池进气压力和工作温度一定的情况下,随着进气流量的增加,进气温度随之升高,电池性能也将得到明显改善;其次,通过比较同一进气压力、进气温度和工作温度下电堆的一致性,得出第十片单电池性能衰减较快.
In order to study the different inlet temperature effects on proton exchange membrane fuel cells performance,firstly,the basic reaction principle of proton exchange membrane fuel cells is analysed;secondly,a proton exchange membrane fuel cells performance test platform is set up and stack experiments are made by changing cathode and anode inlet temperature in the condition that air and hydrogen entrance force is 0. 1 MPa,and fuel cell working temperature is 60 ℃. The experimental results show that the proton exchange membrane fuel cells performance are affected by inlet temperature when the fuel cells inlet pressure and working temperature is constant,with the increase of inlet flow rate,hydrogen and air temperature increased,and the fuel cells performance will be significantly improved.Additionally,by comparing the stack consistency at same inlet pressure,inlet temperature and operating temperature,the results show the tenth single cell performance degradation is faster.
