70 kW燃料电池热电联产系统水热管理研究

质子交换膜燃料电池堆的电效率约为50%，电化学反应剩余的能量要以热量的形式散失，造成巨大能量浪费，开发基于燃料电池的热电联产系统可以高效地产生电力和热水，并显著提高系统的能量效率。在MATLAB/Simulink平台上搭建了70 kW级燃料电池热电联产系统，包括燃料电池电模型、热管理模型和热电联产系统综合动态模型，并开发了一种智能控制算法进行水热管理，将电堆运行温度控制在70 ℃左右，在保证电堆正常运行的前提下，提升热能回收效率并降低系统寄生功率。结果表明该系统可以有效地回收燃料电池反应所产生的废热，在增大外部负载提高电堆电效率的同时，热电联产效率会逐渐增高然后降低，热电联产最高效率可以达到8...
