燃料电池发动机典型故障的故障树分析

The Typical Faults Analysis of Fuel Cell Engine Based on Fault Tree Analysis

故障树分析(FTA)作为系统可靠性、安全性设计与评估的重要方法,用图形演绎的方法表示出系统故障可能原因之间的逻辑关系.本文结合文献中燃料电池故障的分析与实际FCE的结构,对燃料电池汽车(FCV)中的燃料电池发动机(FCE)的典型故障进行分析,旨在为FCE可靠性分析提供有效方法.

As an important method of assessing the reliability and safety of systems,Fault Tree Analysis（FTA） make use of deductive method to express the faults.It shows the graphical and logical relationship between possible causes.Combining the analysis of Fuel Cells＇ faults in references and the particle structure of FCEs（Fuel Cell Engines）,this paper analyses the typical failure of FCEs in FCVs（fuel cell vehicles）,aiming to present a effective method for FCEs＇ reliability analysis.
