Abstract: Direct-hydrogen proton-exchange-membrane fuel cell engines (PEMFCE) is a complicated system full of tradeoff among subsystems. The importance and the state of arts of management system are dissertated from four levels, mechanism analysis of water management, experiential model of stack, simulation of stack and air subsystem, optimization and control of fuel cell engine including system-level water and thermal subsystem. From the aspect of water management, the idea of combining the mechanism modeling, systematical optimization and intelligent control is put forward.

Key words: Proton-exchange-membrane fuel cell engines  Water management  Model  Optimization  Control
