FAILURE DIAGNOSING METHOD AND SYSTEM OF TEMPERATURE SENSOR FOR FUEL CELL

A method and a system for diagnosing a failure of a temperature sensor for a fuel cell are provided. The method includes calculating a heating value that is generated at a fuel cell stack during a predetermined diagnosis time and then calculating a temperature variation of the fuel cell stack from the calculated heating value. A failure of a temperature sensor configured to measure a temperature of the fuel cell stack is then detected based on the calculated temperature variation of the fuel cell stack. 本发明提供了用于诊断燃料电池的温度传感器故障的方法和系统。该方法包括计算在预定诊断时间期间在燃料电池组处产生的发热值，然后根据计算出的发热值来计算燃料电池组的温度变化。然后，基于计算出的燃料电池组的温度变化来检测配置为测量燃料电池组的温度的温度传感器的故障。
