).The flow field plate is manufactured by applying micro-electromechanical systems(MEMS) technology to silicon substrates to etch flow channels without a gold-coating.Therefore
this investigation used MEMS technology for fabrication of a flow field plate and presents a novel fabrication procedure.Various operating parameters
such as fuel temperature and fuel stoichiometric flow rate
are tested to optimize micro PEMFC performance.A single micro PEMFC using MEMS technology reveals the ideal performance of the proposed fuel cell.The optimal power density approaches 232.75 mW·cm
-1
when the fuel cell is operated at ambient condition with humidified
heated fuel.
