The design of a direct carbon fuel cell (DCFC) for continuous operation was successfully executed and is presented in this study. Petroleum coke, an abundant source Canada, used as pneumatically supplied to the anode side cell. open circuit voltage (OCV) reached 1.1 V generated power density 28 mW/cm2 at 700 °C 85 850 °C. After about 180 h cell's performance declined, due loss electrolyte. In n...

Direct methanol fuel cells (DMFC) are getting increasing attention as a possible power source for application in the field of power electronics where the energy requirements are relatively small. The major advantage of the DMFC is their high energy density in comparison to the conventional batteries. In this study, the performance of a passive direct methanol fuel cell was investigated under fi...

A novel proton exchange membrane has been prepared using sulfonated poly(styrene-divinylbenzene) resin(SPSDR)–polyethylene(PE). The membrane is characterized by FT-IR, SEM and TGA/DSC. Water uptake, oxidative resistance, ionic conductivity and methanol permeability are measured to evaluate its performance in a direct methanol fuel cell. The on-set degradation temp...

The possible use of alcohols as direct fuels for fuel cells conjures up images of instantly recharging cellphones and digital cameras from hip flasks, and of alcohol-based electricity generation plants for remote villages, and perhaps, more efficient use of alcohols as motor fuels. The reality of such images is assessed and some recent developments in fuel cells are outlined. Perspectives on th...

Objectives • Develop realistic and internally consistent detailed designs for automotive gasoline fuel processor/ proton exchange membrane (PEM) fuel cell systems and direct hydrogen PEM fuel cell systems by using current-year technology. • Apply Design for Manufacture and Assembly (DFMA) design and costing techniques to compare system designs at low, medium, and high annual production rates. •...

the present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. various methods of hydrogen production for automotive applications have been discussed first. as the hydrogen production is one of the major challenges for application of proton exchange membrane (pem) fuel cells, especially in vehicular indus...

it is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. in this paper, a cogeneration system based on solid oxide fuel cells is examined. the system, including the f...

Direct methanol fuel cells are regarded nowadays as promising energy sources for portable electronic devices. Numerical models can be very useful for addressing the exploration of the fuel cell performance, without the development of many prototypes, which can be very expensive due to the presence of rear materials. Analytical models are particularly suited for investigating the cell performanc...
