This paper presents the expert fault monitoring and intelligent comprehensive control of a proton exchange membrane (PEM) fuel cell (PEMFC) as backup power source for an uninterruptible power supply (UPS) system. The failure status can be shown on the screen of a micro-computer (or a PC) linked with the UPS through an RS-232 and on the control panel of the UPS through LED indicator lights. The proposed...
To analyze and improve the performance of proton exchange membrane fuel cell (PEMFC) stack, this paper conducts research in intelligent comprehensive control of the operational parameters, such as the operating temperature, pressure, mass flows of hydrogen and air for the PEMFC stack, current density, the exhaust emission quantity of reactant gas, and humidity of the hydrogen and air/oxygen. A detailed...
