In practical application, however, the overall efficiency of PEMFC can’t be optimistic, for the electric efficiency of PEMFC is affected by many operational parameters, which result in lower electric efficiency, and besides, waste heat produced in PEMFC accounts for 40%~60% of the whole energy, but the heat is in low grade, so it is difficult to be used.
然而,在实际应用中,质子交换膜燃料电池的燃料综合利用率并不高,其主要原因为质子交换膜燃料电池输出电效率受到各种操作条件的影响,降低了电池堆的电效率,同时质子交换膜燃料电池在发电的过程中产生热,这部分余热占总能量的40%~60%,但由于余热的品位低,利用困难,因而降低了燃料的利用率。
