Abstract

The invention discloses an anode gas supply device and method of a fuel cell engine. Startup purging, hydrogen circulation, tail gas emission and shutdown purging of the galvanic pile are realized through a hydrogen inlet pressure regulating branch, a gas in-pile branch, an air purging branch, a gas circulation branch, a gas out-pile branch and a gas tail gas exhaust branch; therefore, enough hydrogen flow, pressure and internal suitable humidity are provided for normal operation of the fuel cell, high-efficiency stable operation of the fuel cell engine is realized without frequent load changeof a circulating pump, good power generation characteristics are ensured, and the hydrogen-rich fuel cell engine has the characteristics of high hydrogen utilization rate, strong tail gas exhaust effect and the like.

Description

technical field [0001] The invention belongs to the field of fuel cell technology, and more specifically relates to an anode gas supply device and method for a fuel cell engine. Background technique [0002] In recent years, with the development of new energy technologies, proton exchange membrane fuel cell power generation technology has attracted much attention due to its advantages of high energy density, zero emission, and regeneration. Proton exchange membrane fuel cells are divided into two types: water circulation cooling and air cooling. Among them, water-cooled fuel cells have the characteristics of high energy density and long service life, so fuel cells have broad application prospects in stationary power generation devices, new energy vehicles and other fields. [0003] The fuel cell engine generates electrical energy through the electrochemical reaction of hydrogen on the anode side and oxygen on the cathode side. The hydrogen supply module on the anode side is ...
