Study of 1.26 kw - 24 VDC Proton Exchange Membrane Fuel Cell's (PEMFC'S) Parameters Output Behaviour : Composition & Temperature

Abstract

The eternally intensifying exigency for electrical energy and the mount in the electricity expenditures due to the recent transience of the oil charges over and above to the desensitizing of the air standard resulting from the ejections of the obtaining energy transmutation devices have amplified exploration into substitute renewable proveniences of electrical energy. In today, there are six antithetical types of fuel cell technologies attainable – molten carbonate fuel cells; phosphoric acid fuel cells; solid oxide fuel cells; alkaline fuel cells; polymer electrolyte membrane fuel cells and direct methanol-air fuel cells. Polymer electrolyte membrane (PEM) fuel cells – also known proton exchange membrane fuel cells, which are one of the uncomplicated types of fuel cell. PEMFC’s output power is unpredicted on nonlinearly on its output voltage and current. The output current of a proton exchange membrane fuel cell stack relies on the load located on that particular stack. This paper presents a 1.26 kW -24 Vdc PEMFC system and DC – DC boost converter topology used in 1.26 kW PEM fuel cell to fortify that the zenith obtainable output power from a PEM membrane fuel cell is distributed to a load during a power outage bridging the start-up time and to optimize the health of the fuel cell membrane stack. A 1.26 kW – 24 Vdc PEMFC system is considered in this study as well as investigate how the output behaves.
