Solid-state synthesis of Pt/C cathode catalysts for direct methanol fuel cells

Abstract

To alleviate the world's current energy crisis, fuel cells play a significant role. The efficiency of a fuel cell primarily depends on the electrochemical catalytic activity of the catalysts used....

Development of Membrane Electrode Assembly with Double-Catalytic Layer for Micro Direct Methanol Fuel Cell

“…By adding Vulcan XC-72R, Ketjen Black EC 300J, and Black Pearls 2000 carbon blacks to the cathode catalyst layer of Pt black, Wang et al were able to more than double the power density of the prepared MEA [14,15]. Most efforts were put into tuning micropore structure and improving electrical conductivity through use of carbon materials [10,[16][17][18]. In these ways, the reactive surface area of the catalysts and their electrochemical activity are improved, while Ohmic loss is reduced to as little as possible.…”

Proton conduction of an ionic HOF with multiple water molecules and application as a membrane filler in direct methanol fuel cells

“…As a fuel, methanol can directly convert chemical energy into electrical energy. Since the production process of methanol is simple and of low cost and it is easy to store and transport methanol, direct methanol fuel cells (DMFCs) 5–9 have great potential for development and have become a hot spot of new energy research.…”
