The development of a generalized steady-state electrochemical model of a polymer electrolyte fuel cell or proton exchange membrane fuel cell (PEMFC) system is presented by R.F Mann et al. to predict the output voltage of a single Ballard Mark V cell as a function of the major variables like current density, pressure of the reactant gases and working temperature more efficiently (Mann et al. 200...

Oxygen transport across the cathode gas diffusion layer (GDL) in polymer electrolyte membrane (PEM) fuel cells was examined by varying the O2/N2 ratio and by varying the area of the GDL extending laterally from the gas flow channel under the bipolar plate (under the land). As the cathode is depleted of oxygen, the current density becomes limited by oxygen transport across the GDL. Oxygen deplet...

The paper describes an EasyTest cell developed for simple, safe and inexpensive to run testing and optimisation of the active materials (catalysts, catalytic supports, polymer membrane electrolytes) and electrode structures utilized in PEM Fuel cells and Electrolysers. The main advantages of the new EasyTest technique are demonstrated by a comparative study on the performance of two types of me...

The recent wave of interest in sustainability has brought the benefits of fuel cells into the public sphere. Polymer electrolyte membrane fuel cells provide clean and renewable energy, but are subject to degradation. Given the possibilities for use in remote applications, it is necessary to understand and minimize degradation of fuel cell components. Here we analyze common types of degradation ...

Incremental advancements fuel cells materials and manufacture processes now suitable for commercialization. However, the complex operation of cell systems automotive has some open issues yet. This work develops compares three...

In this study, a catalyst was synthesized on carbon nanofibers [CNFs] with a herringbone-type morphology. The Pt/CNF catalyst exhibited low hydrophilicity, low surface area, high dispersion, and high graphitic behavior on physical analysis. Electrodes (5 cm2) were prepared by a spray method, and the durability of the Pt/CNF was evaluated by fuel starvation. The performance was compared with a c...
