The invention discloses a fuel cell protection system and method, an electric vehicle and a storage medium. The fuel cell protection system comprises a fuel cell pack, a DC-DC conversion module electrically connected with the fuel battery pack, a collision detection module used for detecting whether the fuel cell stack is collided or not to obtain a collision detection signal, and a control moduleelectrically connected to the collision detection module and used for receiving the detection module and enabling the fuel battery pack and the DC-DC conversion module to be disconnected or kept connected according to the detection signal. The fuel cell stack and the DC-DC conversion module are controlled to maintain connection or disconnection through the collision detection signal so as to prevent short circuit and even explosion caused by a fact that the fuel cell stack and the DC-DC conversion module maintain connection during collision, and the safety of the fuel cell stack is improved.

    本发明公开了一种燃料电池保护系统、方法、电动汽车及存储介质,燃料电池保护系统,包括:燃料电池组;DC‑DC转换模块,电连接与所述燃料电池组;碰撞检测模块,用于检测所述燃料电池组是否发生碰撞以得到碰撞检测信号;控制模块,电连接于所述碰撞检测模块,用于接收所述检测模块并根据所述检测信号控制所述燃料电池组和所述DC‑DC转换模块断开连接或保持连接。本发明通过碰撞检测信号来控制燃料电池组和DC‑DC转换模块保持连接或断开连接,以防止发生碰撞时燃料电池和DC‑DC转换模块保持连接导致短路乃至发生爆炸,以提高燃料电池组的安全性。
