Abstract

The invention provides a steam-water separator for a proton exchange membrane fuel cell engine hydrogen subsystem. The steam-water separator at least comprises a separator body, an inlet connection pipe, a lower baffle and an upper baffle; the inlet connection pipe is connected with the separator body and extends to the bottom of the separator body, and a gap is formed between the inlet connectionpipe and the bottom of the separator body; the upper baffle is connected with the separator body, and a gap is formed between the upper baffle and the inlet connection pipe; the lower baffle is connected with the inlet connection pipe, and a gap is formed between the lower baffle and the inlet connection pipe. The steam-water separator for the proton exchange membrane fuel cell engine hydrogen subsystem has the advantages of being small in size, low in resistance drop, simple in structure, high in water-dividing efficiency, free of maintenance and the like, and can assist in achieving low-temperature startup.

Description

technical field [0001] This patent relates to the field of proton exchange membrane fuel cell engines, more specifically, it relates to a steam-water separator for hydrogen subsystems of proton exchange membrane fuel cell engines used in vehicles and ships. Background technique [0002] A proton exchange membrane fuel cell engine system is a power generating device that directly converts the chemical energy in a fuel (usually hydrogen or methanol) into electrical energy through an electrochemical reaction. Unlike traditional power generation devices, it does not need to convert the chemical energy in the fuel into heat energy and then into electricity. Therefore, compared with traditional power generation devices, fuel cells have the significant advantages of high energy conversion efficiency and no pollutant emissions. [0003] Studies have shown that proper humidification of hydrogen can significantly improve the performance and life of proton exchange membrane fuel cells...
