A novel, physically strong, quaternary-ammonium-functionalised radiation-grafted ETFE alkaline anion-exchange membrane (AAEM) has been developed for application in fuel cells without undesirable addition of MOH into the anode fuel stream, thereby facilitating stable performances and long term operational lifetimes. A promising H2/O2 fuel cell peak power performance of 130 mW cm -2 was obtained ...

direct electron transferring of glucose oxidase was investigated   on reduced graphene and graphene oxide templates. the direct electrochemistry   glucose oxidase on   graphene showed a cyclic voltammograms corresponding to the fad/fadh 2   redox couple with an anodic, cathodic and formal potential of -430, -460 and   -445 mv, respectively in 0.1 m phosphate buffer solution and air saturated   ...

A novel alkaline polymer has been developed as an interfacial material for use in the preparation of metal-cation-free alkaline membrane electrode assemblies (MEAs) for all-solid-state alkaline fuel cells (AFCs) with long-term performance stability.

Direct alkaline alcohol fuel cells (DAAFCs) have attracted increasing interest over the past decade because of their favourable reaction kinetics in alkaline media, higher energy densities achievable and the easy handling of the liquid fuels. In this review, principles and mechanisms of DAAFCs in alcohol oxidation and oxygen reduction are discussed. Despite the high energy densities available d...

Passive direct methanol fuel cell (DMFC) is considered as an attractive power source for portable devices. In this study, a transient multiphase model for passive alkaline anion exchange membrane DMFC (AAEMDMFC) is developed. The results show that the power density decreases during the operation and is more difficult to maintain stable with higher current density or lower voltage. The fuel effi...
