Abstract

The invention discloses a tail gas emission device of a hydrogen fuel cell engine, which comprises an electronic throttle valve, an exhaust tail pipe, a flow guide pipe, a three-way catalyst, a sealing ring, a spring and the like. By adopting a multifunctional integrated design, the device has the functions of intensively discharging emissions of a fuel cell engine, eliminating hydrogen leaked by the galvanic pile and residual hydrogen in electrochemical reaction, realizing negative pressure ventilation of the galvanic pile protection cover without auxiliary electric energy and the like, and is simple in structure, high in applicability, low in technical difficulty, convenient to install and transport, low in manufacturing and maintenance cost and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of fuel cell engines, and in particular relates to an exhaust emission device for hydrogen fuel cell engines. Background technique [0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy present in fuel and oxidant into electrical energy through an electrochemical reaction. It has the advantages of high energy conversion efficiency, high energy density, low vibration and noise, and zero emissions. Therefore, hydrogen fuel cell is regarded as a clean and efficient ideal power device in the 21st century, and it is an important way to solve the two major problems of resource scarcity and pollution deterioration. It has broad development and application prospects in the fields of new energy vehicles and green ships. [0003] The fuel cell stack will inevitably leak a small amount of hydrogen to the outside world. The accumulation of hydrogen may cause fire, explosion...
