Abstract

The pneumatic proportional pressure reducing valve is the main pressure control component in the fuel cell gas supply system, which directly affects the performance of the entire fuel cell system. Based on the research background of the hydrogen oxygen fuel cell gas supply system, a set of pneumatic proportional pressure reducing valves suitable for hydrogen oxygen gas environments was designed. Through structural design and multi-parameter analysis, the structural parameter design optimization and characteristic analysis of the proportional valve were proposed. It can provide high-precision and high stability gas control capabilities for fuel cell systems, and provide support for engineering applications.
