Disclosed in the present application are a fuel cell module, an assembly positioning assembly and a vehicle. The fuel cell module comprises a case, a cell stack, an insulating support assembly and two or more cross beams, wherein the insulating support assembly is arranged between the case and the cell stack, and the insulating support assembly is in contact with all side surfaces of a stack core of the cell stack and all inner side surfaces of a bearing frame, such that the side surfaces of the stack core can be supported and an interlayer slip of the cell stack can be resisted; and gaps are formed between the insulating support assembly and both an end plate and a current collection plate of the cell stack, and the gaps can serve as buffer spaces to prevent the insulating support assembly from being damaged by the impact of the end plate and the current collection plate. The two or more cross beams are arranged between a blind end of the cell stack and the case, with two ends of each cross beam both being connected to the bearing frame; and the bearing frame applies a fastening force towards an air intake end plate assembly by means of the cross beams, thereby achieving the packaging of the case.

Disclosed herein are a gas diffusion layer, a preparation method therefor, and a membrane electrode. The gas diffusion layer comprises a substrate, and a microporous layer attached to at least a portion of a surface of the substrate. Raw materials of the microporous layer comprise a phosphorus-containing compound solution; the mass concentration of the phosphorus-containing compound solution is 45% to 47%, and the mass of the phosphorus-containing compound solution is 2% to 5% of the total mass of the raw materials of the microporous layer. In the present application, the phosphorus-containing compound is placed in the gas diffusion layer. Due to the porous structure and good gas permeability of the gas diffusion layer, the phosphorus-containing compound can be fully diffused therein, increasing the opportunities for contact with free radicals, thereby effectively reducing the attack of free radicals on a proton exchange membrane, further protecting the chemical structure of the membrane, and alleviating the speed of decrease of proton conductivity to a certain extent. Therefore, with regard to a membrane electrode containing the described gas diffusion layer, both the durability and the electrical performance of the membrane electrode are considered.

A coolant drain system of an ion filter may prevent deterioration in filtration performance of an ion exchange resin and improve durability thereof. The coolant drain system is operated in such that, when electrical conductivity of coolant circulating through a fuel cell stack is equal to or higher than a predetermined level, the coolant circulates through the inside of the ion filter such that metal ions of the coolant are easily removed by the ion exchange resin. When electrical conductivity of the coolant is reduced to be lower than the predetermined level, the coolant remaining inside the ion filter is drained to a pressurized reservoir using the pressure of air supplied from the pressurized reservoir.
