Abstract

The invention relates to an integrated hydrogen supply system of a fuel cell; the system comprises an integrated shell, the integrated shell comprises a gas-water separator shell on the lower portion, an ejector shell on the upper portion and a buffer cavity shell, and a hydrogen circulating pump is installed on the ejector shell; a hydrogen return inlet is formed in one side of the gas-water separator shell, a water outlet is formed in the bottom of the gas-water separator shell, a hydrogen return outlet is formed in the top of the gas-water separator shell, and a labyrinth structure is installed in the gas-water separator shell and used for separating water in hydrogen-containing mixed gas; the gas-water separator shell, the ejector shell and the buffer cavity shell are integrated into a whole, and the hydrogen circulating pump is integrated on the ejector shell, so that the volume is small, the hydrogen circulating pump can be mounted and used in some areas with small spaces, connecting pipelines between hydrogen supply components of a hydrogen path are omitted, the gas transmission distance is short, and the energy loss in the transmission process is reduced. And the pressurizing efficiency is improved, the mounting efficiency is high, and the freezing blockage condition caused by accumulated water in the pipeline when the temperature is too low is avoided.

Description

Technical field: [0001] The invention relates to a fuel cell integrated hydrogen supply system. Background technique: [0002] At present, the development of new energy fuel cell vehicles is considered an important link in the transformation of transportation energy and power. In order to ensure the normal operation of fuel cell engines, fuel cell engines generally require auxiliary systems such as hydrogen supply subsystems, air supply subsystems, and circulating water cooling management subsystems. . Fuel cells generate electrical energy through the electrochemical reaction between combustible substances (hydrogen) and oxygen in the air. After the fuel cell reacts, the exhaust gas contains a large amount of hydrogen. If these hydrogen are directly discharged into the atmosphere, on the one hand It is a waste of energy. On the other hand, it causes pollution to the environment. Third, hydrogen is flammable and explosive, which will cause danger. Therefore, it is necessary ...
