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...

The alkaline thermal treatment of biomass has recently been proposed as a novel method for producing high purity H2 with suppressed COx formation under moderate reaction conditions (i.e., 523 K and ambient pressure). This technology has a great potential for sustainable bioenergy production because it can handle a wide range of feedstocks including biomass and biogenic wastes with high water co...

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...

Direct alcohol fuel cells have been attracting enormous research interest as power sources for vehicles and portable electronic devices because alcohols are readily available, their storage and transport can be easily handled with the existing fuel infrastructure, and they commonly have high mass-specific and volumetric energy densities. Methanol is the most studied fuel for direct alcohol fuel...

Nanotechnology allows the synthesis of nanoscale catalysts, which offer an efficient alternative for fuel cell applications. In this laboratory experiment, the student selects a cost-effective anode for fuel cells by comparing three different working electrodes. These are commercially available palladium (Pd) and glassy carbon (GC) electrodes, and a carbon paste (CP) electrode that is prepared ...

Alkaline anion–exchange membranes (AAEM) for alkaline polymer electrolyte fuel cells (APEFC) were successfully prepared using electron beam irradiated poly(ethylene–co– tetrafluoroethylene) precursor films grafted with vinylbenzyl chloride (VBC) monomer. The resulting chloromethyl groups were subsequently reacted with trimethylamine to form quaternary ammonium anion–exchange functional head–gro...

Hypoglycemia commonly causes brain fuel deprivation, resulting in functional brain failure, which can be corrected by raising plasma glucose concentrations. Rarely, profound hypoglycemia causes brain death that is not the result of fuel deprivation per se. In this issue of the JCI, Suh and colleagues use cell culture and in vivo rodent studies of glucose deprivation and marked hypoglycemia and ...
