The methanol oxidation reaction has been the subject of a large number of studies in the past.[1, 2] Early work revealed a complex reaction mechanism,[3–6] indicating the electrocatalysis of methanol oxidation as the most difficult task in the realization of a direct methanol fuel cell (DMFC). Several metal catalysts were proposed for the reaction, most of them based on modifications of Pt with...

In this work, a direct methanolehydrogen peroxide fuel cell is developed and tested. Theoretically, it is shown that the use of hydrogen peroxide in a direct methanol fuel cell (DMFC) not only increases the cell's voltage from 1.21 V to 1.76 V, but also reduces the activation loss of the reduction reaction as a result of two-electron transfer. Experimentally, it is demonstrated that the fuel ce...

The novel oriented electrospun nanofiber membrane composed of MOFs and SPPESK has been synthesized for proton exchange membrane fuel cell operating at high temperature and anhydrous conditions. It is clear that the oriented nanofiber membrane displays the higher proton conductivity than that of the disordered nanofiber membrane or the membrane prepared by conventional solvent-casting method (wi...

Platinum (Pt) is the common catalyst used in a direct methanol fuel cell (DMFC). However, Pt can lead towards catalyst poisoning by carbonaceous species, thus reduces the performance of DMFC. Thus, this study focuses on the fabrication of a new composite TiO2 carbon nanofiber anodic catalyst support for direct methanol fuel cells (DMFCs) via electrospinning technique. The distance between the t...

Current catalysts for the alcohol oxidation in fuel cells (typically noble metals-based) are susceptible to poisoning with intermediates like CO. Hence we decided to find superseded catalysts for methanol oxidation based on incorporation of mixed oxides. In this research, a nano-size perovskite SrFeO3-δ (SrFeO3<su...
