Abstract

The invention relates to a fuel cell hydrogen supply and hydrogen return integrated system comprising an integrated shell which comprises a gas-water separator shell on the lower portion, an ejector shell on the upper portion and a buffer cavity 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 to be used for installing hydrogen path hydrogen supply components, a first proportional valve and a second proportional valve are integrated on the buffer cavity shell, the volume is small, the gas-water separator can be installed and used in some areas with small spaces, connecting pipelines between the hydrogen path hydrogen supply components are omitted, and the gas transmission distance is short. And the energy loss in the transmission process is reduced, the pressurization efficiency is improved, the installation efficiency is high, and the icing 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 an integrated system for supplying hydrogen and returning hydrogen to a fuel cell. 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...
