[0003] In the prior art, the baffle type separator with small pressure loss is generally used, and one to three baffles are generally installed. With the increase of the number of baffles, the separation efficiency will be slightly improved, but at the same time, the resistance will increase and the gas The loss of hydraulic pressure increases

Abstract
The embodiment of the invention discloses a gas-water separator and a fuel cell hydrogen supply system, the gas-water separator comprises a shell, a first baffle plate and a second baffle plate, the shell is provided with a cavity, a gas-liquid mixture inlet, an exhaust port and a liquid discharge port, the first baffle plate is arranged in the cavity, and the second baffle plate is arranged in the cavity. The first baffle and the gas-liquid mixture inlet are oppositely arranged in the first direction, the bottom end of the first baffle and the inner wall face of the cavity are spaced, and the first baffle is provided with a first side face and a second side face which are oppositely arranged in the second direction. At least one of the first side face of the first baffle and the second side face of the first baffle is separated from the inner wall face of the shell, the second baffle is arranged in the cavity, and the bottom end of the second baffle is separated from the inner wall face of the cavity. According to the gas-water separator disclosed by the invention, the flow resistance can be reduced while the separation efficiency is improved, and stable and efficient operation of a hydrogen circulation system is ensured.
Description
technical field [0001] The invention relates to a new energy fuel cell, in particular to a gas-water separator and a fuel cell hydrogen supply system. Background technique [0002] The hydrogen circulation circuit of the hydrogen fuel cell system usually uses a hydrogen circulation pump or an ejector as a hydrogen circulation device. The ejector loop based on the ejector has been favored by many researchers in the hydrogen circulation system of the hydrogen fuel cell, and has been widely used. In the hydrogen circulation system of the hydrogen fuel cell, since the exhaust gas discharged from the anode of the stack contains mixed gases (hydrogen, nitrogen and moisture) under saturated humidity, an important condition to maintain the stable operation of the stack is to maintain the temperature required by the stack. and humidity, so the circulating exhaust gas needs to use a gas-water separator to separate the liquid water in the exhaust gas before entering the ejector.
