氢气杂质CO对质子交换膜燃料电池性能影响建模
Modeling for effect of CO in hydrogen on performance of PEMFC
摘要
Abstract
CO poisoning mechanism has been investigated. The influences for CO on the activation loss, ohmic loss, and concentration loss were discussed separately, and then the model for the effect of CO on the performance of PEMFC was obtained. The cell voltage dropped severely in the presence of CO at moderate current density, That is due to that the decrease of limit current density caused by CO coverage. This model is validated by a test on a 50 cm~2 single cell in the presence of 1 × 10~(-6) CO in hydrogen,and the output of the model shows a good agreement with experiment results.关键词
