Abstract:
... Direct methanol fuel cells (DMFCs) and direct ethanol fuel cells (DEFCs) have drawn great attention as promising power sources for mobile and portable devices. However, the anodic reactions in DMFCs and DEFCs, namely the methanol oxidation reaction (MOR) and ethanol oxidation reaction (EOR), suffer from notoriously sluggish kinetics which seriously limited their large-scale applications. In this r ...

Abstract:
... Methanol crossover is one of the largest problems in direct methanol fuel cells (DMFCs). Methanol passing from the anode to the cathode through the membrane is oxidized at the cathode, degrading the DMFC performance, and the intermediates of the methanol oxidation reaction (MOR) cause cathode catalyst poisoning. Therefore, it is essential to develop a cathode catalyst capable of inhibiting MOR whi ...

Abstract:
... Hydrogen is yet to be widely accepted as a fuel for everyday operation due to stringent safety regulations involved around it. In the meanwhile, methanol could be a potential fuel of the future. In this work, an extensive thermodynamic investigation on an energy storage system with a reversible solid oxide stack at its core is presented. The current investigated system can operate either as an ele ...
