... to those nanofibers. The experiments demonstrate that ionomer nanofibers have proton conductivities that exceed those of the bulk form of the ionomer by more than an order of magnitude. A new model of a proton exchange membrane fuel cell is presented here that predicts the effect of nanofibers on cell...

... of the Pt–H system. Then, the H 2 dissociative adsorption process is obtained using the nudged elastic band approach. The modeling of the nanocomposites in the CLs is a multiscale problem. The nanoscale models are used for investigating the structural evolution and the interactions between Pt/C particles...

...Eric S. Greene; Wilson K. S. Chiu; A. Alan Burke; Maria G. Medeiros; Louis G. Carreiro Solid oxide fuel cells (SOFCs) offer many potential benefits as an energy conversion device. This paper addresses experimental validation of a numerical SOFC model that has been developed. Results are compared...

...C. Graf; K. A. Friedrich; A. Vath; N. Nicoloso A dynamic model of a polymer electrolyte fuel cell hybrid system has been developed within MATLAB - SIMULINK . Components are modeled using electrochemical and mass transport as well as heat transfer equations. The implemented equations describe...

...Jaroslaw Milewski; Andrzej Miller This paper sets out the results of mathematical modeling and numerical simulations with regard to the influences of the type and thickness of electrolyte on Solid Oxide Fuel Cell Hybrid System (SOFC-HS) performance. A change of electrolyte materials can result...
