Description

Technical field[0001]The invention belongs to the field of new energy technologies, and more relates to a fuel cell, and more particularly to a fuel cell gas water separator and a preparation method thereof.Background technique[0002]The fuel cell engine is a power generating device that directly converts hydrogen and oxygen in the internal reactivity of the electric stack into electrical energy. In order to improve the hydrogen utilization rate of the fuel cell system, the mainstream mode is used to use a hydrogen gas closed end cycle mode. This method can not only improve the utilization of hydrogen, but also ensure uniform in the anode side hydrogen distribution.[0003]The existing hydrogen generates cannot be effectively separated from water to water, resulting in a large amount of water into the electric pile, resulting in water flooding, resulting in lowening power loss. At the same time, an electrochemical reaction is electrochemical reaction occurs during the electrochemical r...

AI Technical Summary

Problems solved by technology

[0003] The existing hydrogen return device cannot effectively separate the remaining hydrogen that has not participated in the reaction from water, causing a large amount of water to enter the stack and cause flooding, resulting in a decrease in the power of the stack

At the same time, when the electrochemical reaction occurs inside the stack, the fluid of the anode and the cathode must have a certain temperature to ensure the stable performance of the fuel cell system; and after the shutdown, the water will freeze in the low temperature environment and block the drain of the gas-water separator, resulting in fuel The battery system starts abnormally at low temperature
