Abstract
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.
