Background

A fuel cell hydrogen powered vehicle refers to a vehicle that uses hydrogen as an energy source. The hydrogen energy automobile generally comprises two sets of power assemblies, wherein one set of power assembly is a galvanic pile assembly which takes hydrogen as an energy source to carry out chemical reaction to generate electric energy, and the other set of power assembly is a motor assembly which takes a driving motor as a direct power source to provide driving force for the whole automobile. Therefore, hydrogen powered vehicles typically require two sets of suspension systems: a motor suspension system and a pile suspension system.

In a fuel cell hydrogen energy automobile, a stack suspension system refers to a device which is arranged between a fuel cell system (called a stack for short) and a vehicle body or an auxiliary frame and plays roles of supporting, limiting and isolating the fuel cell system.
