Here, the fluid-related component is one of the components of the fluid-related system. For example, the fluid-involving system can be a fuel cell system, and the fluid-involving components can be a fuel cell stack in the fuel cell system. Firstly, analyze various potential dangerous working conditions of the fuel cell stack. The operability analysis method, that is, HAZOP (Hazard, Operability, hazard and operability) analyzes the fuel cell stack to obtain possible failures of the fuel cell stack (that is, a variety of potentially dangerous conditions). In addition, it can also Analyze the ...
