The invention provides a gas regulation assembly, a fuel cell and a vehicle. The gas regulation assembly comprises an integrated module, wherein the integrated module is provided with a gas inlet and a gas outlet which are communicated with each other, the gas inlet comprises a first gas inlet used for being connected with a gas source and a second gas inlet used for being connected with an outlet of a cell stack, and the gas outlet is used for being connected with an inlet of the cell stack. The first gas inlet enables high-pressure hydrogen in the gas source to enter the integrated module through the first gas inlet, the second gas inlet is connected with the outlet of the cell stack, the second gas inlet enables residual gas after cell stack reaction to pass through a steam-water flow divider and a circulating device and then enter the integrated module again, and the reacted gas can enter the cell stack again to react, so that the temperature and humidity of the gas are improved. Meanwhile, various gas supply control components are integrated together, so that the gas leakage rate of an external pipeline joint is reduced, safe and reliable operation of the system is ensured, the overall size and weight are reduced, and the power density and the power generation efficiency are improved.

    本发明提供了一种气体调节总成、燃料电池和车辆,气体调节总成包括:集成模块,集成模块上设置有相互连通的进气口和出气口,进气口包括用于与气源连接的第一进气口和用于与电堆出口连接的第二进气口,出气口用于与电堆入口连接。第一进气口,能够使得气源中的高压氢气能够通过第一进气口进入集成模块内,第二进气口与电堆的出口相连接,第二进气口能够将电堆反应后的剩余气体在通过汽水分流器和循环装置后再次接入集成模块上,使得反应后的能够再次进入电堆中反应,进而提升了气体的温度和湿度。同时将多种气体供气控制部件集成在一起,降低外部管路接头的漏气率,保证系统安全可靠运行,减少总体的体积及重量,提高功率密度及发电效率。
