Objectives • Research, develop, assemble, and test a 50 kW net polymer electrolyte membrane (PEM) fuel cell stack system comprised of a PEM fuel cell stack and the supporting gas, thermal, and water management subsystems. The PEM fuel cell stack system will be capable of integration with at least one of the fuel processors currently under development by Hydrogen Burner Technology (HBT) and Arth...

This paper analyzes the possibility of using a nonlinear controller to mitigate the current ripple of an inverter system powered by a Polymer Electrolyte Membrane Fuel Cell (PEMFC) stack. Hybrid and fuel cell technologies need to be merged in Hybrid Power Sources (HPS) to assure high performance regarding the PEMFC energy efficiency and PEMFC life cycle. The nonlinear controller is designed bas...

Among a number of alternative energy sources, hydrogen is treated as one of the most promising candidates, due to the reason that it can be applied to a fuel cell as an input to provide electricity through an electrochemical reaction. On top of that, high conversion efficiency up to 40 to 60% is seen in a fuel cell. The first application of a Proton Exchange Membrane (PEM) fuel cell was as an a...

The decreasing abundance of conventional energy resources nature, such as crude oil, natural gas, and coal, is putting forward the issues shortcoming for future. With a sentiment this, most researchers are now directing either on non-conventional that already prevail or invent it. promising resource hydrogen energy, which can be used in fuel cell to get electricity. Therefore, number light deve...

In this paper a 300W PEM FC Stack dynamic model is developed and implemented in MATLAB/Simulink. Using semi-empirical equations for modelling a Proton Exchange Membrane (PEM) fuel cell is proposed for providing a tool for the design and analysis of fuel cell stack systems. The modelling results are compared with experimental results. The comparison shows good agreements between the modelling re...

With the increasing application of distributed energy resources and information technologies in the electricity infrastructure, innovative possibilities for incorporating the demand side more actively in power system operation are enabled. At the residential level energy costs could be reduced with intelligent price-based control concepts (demand response). A promising, controllable, residentia...

Proton transfer in polymer electrolyte membrane is an essential mechanism fuel cell (PEMFC). The development of PEM mostly relies on modification with proton conductive species followed by casting. This brings the random existence to result a limit conductivity. present work proposes alignment species, i.e., donor and acceptor chains, through surface-initiated polymerization so that proceeds ef...

The proton exchange membrane fuel cell(PEMFC) is a type of fuel cell being developed for transport applications as well as for stationary fuel cell applications and portable fuel cell applications. Recently, the research of PEMFC has been more focused on describing the characteristics and building models of fuel cells, which are important application but obviously not enough. This paper present...

Integration of fuel cell stack with an inverter is complex in nature. A number of factors have to be taken into account in designing the inverter as well as during the integration. One of these factors is ripple current which could affect the life of the fuel cell stack if there is fuel and/or oxidant starvation. In this paper an inverter topology is investigated which significantly reduces or ...
