At high temperature, the reaction speed of fuel gas and oxygen is accelerated to realize power supply at high temperature, but at high temperature, the battery is easy to explode due to overlarge air pressure in the inner cavity of the battery. The explosion limit of a battery is related to temperature and pressure: in the case of air-mixed hydrogen, an explosive mixture exists at a hydrogen concentration of about 4 to 75% by volume hydrogen (at room temperature and atmospheric pressure). Because of the compact construction of the fuel cell system, in order to minimize this risk, a series of safety precautions, primarily primary and secondary explosion protection measures, are taken in the case of the fuel cell systems of the prior art. The primary explosion-proof measure is generally to prevent the formation of, or at least reduce the risk of, an explosive atmosphere, and the secondary explosion-proof measure is generally to prevent the ignition of the explosive atmosphere, i.e. to avoid an effective ignition source.
Most of the explosion-proof measures or components on the market are implemented from the control of the explosive atmosphere itself, resulting in more complex structures and greater system weight, most of which are structurally complex, costly, poorly resistant to high temperatures, and do not yet provide one hundred percent explosion protection. In addition, once the inside of the battery exceeds the limit gas pressure, the explosion-proof device or the battery cannot be reused in general even if the battery does not explode.
