The contact pressure between bipolar plates (BPPs) and a membrane electrode assembly (MEA) has key impact on Proton Exchange Membrane Fuel Cell (PEMFC) performance. However, it is difficult to obtain the combined with operating temperature action via finite element analysis (FEA) model, resulting in limited calculation resources for problem of multiscale thermo-mechanical coupled full-dimension...

The objective of this project is to create clean fuel for transportation using hydrogen powered by solar energy. Hydrogen has been generated by solar photovoltaic (PV) array and then collected for data analysis to demonstrate efficiency of the hydrogen production in all the steps of the experiment. The hydrogen produced from the electrolysis process was either stored in a metal hydride canister...

Integration of a reformer and a proton exchange membrane fuel cell (PEMFC) is problematic due to the presence in the gas from the reforming process of a slight amount of carbon monoxide. Carbon monoxide poisons the catalyst of the proton exchange membrane fuel cell subsequently degrading the fuel cell performance, and necessitating the sublimation of the reaction gas before supplying to fuel ce...

This paper investigates the performance of a high temperature proton exchange membrane PEM fuel cell. Both experimental work and numerical simulation are conducted. The high temperature proton exchange membrane is based on polybenzimidazole PBI doped with phosphoric acid. A single cell with triple serpentine flow channels was operated at steady state at various levels of temperature, pressure, ...

Proper temperature control of Proton Exchange Membrane Fuel Cells is a crucial factor for optimizing fuel cell performance. This paper describes a model-based characterization of the equilibrium points of an open-cathode fuel cell system. Phase plane analysis of the nonlinear model versus a linearized model around different points of operation shows the potential of approximating the nonlinear ...

A state-of-the-art Chinese fuel cell city bus, using a hybrid power system is proposed. This comprises a proton exchange membrane fuel cell and Ni/MH batteries to combine the high energy density of fuel cells with the high power density of batteries. A dc/dc converter is placed between the fuel cell and the battery to control the electric power flow. This paper presents a novel control strategy...
