质子交换膜燃料电池阳极尾排控制综述

Review of Anode Exhaust Strategy in Proton Exchange Membrane Fuel Cell System

质子交换膜燃料电池具有发电效率高、环境污染少等优点,具有广阔的应用前景。但在运行中,氮气和水会透过质子交换膜扩散到阳极,若长时间不排出后会导致电堆性能下降,若频繁排出则会降低氢气利用率。本文针对在燃料电池应用中的尾排控制策略进行了归纳和综述。

The proton exchange membrane fuel cell has the advantages of high power generation efficiency and less environmental pollution and has broad application prospects.However,in operation,nitrogen and water will diff use to the anode through the proton exchange membrane.If not discharged for a long time,the performance of the reactor will be degraded;if discharged frequently,the utilization rate of hydrogen will be reduced.In this paper,tail-row control strategies in fuel cell applications are summarized and reviewed.
