Fuel cell short circuit diagnosis method, system and equipment and readable storage medium

The invention discloses a method for diagnosing short circuit of a fuel cell. The method comprises the following steps: continuously collecting minimum single voltage signals of the fuel cell; according to the lowest monomer voltage signal, calculating a monomer voltage change rate in a pre-calibrated time period; and judging whether the change rate in the single voltage period is greater than the maximum change rate of the pre-calibrated minimum single voltage or not, if so, performing short circuit on the fuel cell stack and judging the short circuit type, and if not, calculating the change rate of the single voltage in the pre-calibrated time period again according to the minimum single voltage signal. The invention also discloses a fuel cell short circuit diagnosis system, computer equipment and a computer readable storage medium. According to the invention, the existing parts in the fuel cell system can be utilized to judge whether the fuel cell is short-circuited or not in real time. 本发明公开了一种燃料电池短路的诊断方法
