Micro DMFC for Portable Applications
ECS Meeting Abstracts, 2019Objective and results Methanol fuel cell systems have the potential of being part of a portable energy system with both high energy density and fast refueling. A hearing aid is an example of a device where fast and easy refueling/recharging and high energy density is an important requirement.

DMFC with Hydrogen Peroxide Cogeneration
Journal of The Electrochemical Society, 2010The process of H 2 O 2 generation in the direct methanol fuel cell (DMFC) composed of the "Black Pearls 2000" gas-diffusion cathode, washed by sodium chloride brine or sea water for O 2 electroreduction and the half-membrane-electrode assembly with the Nafion 115 cation-exchange membrane, hot-pressed on one side with the carbonaceous gas-diffusion ...

On the question of MEA preparation for DMFCs
Journal of Power Sources, 2004To get information for the development of a continuous MEA fabrication sequence various preparation strategies are investigated. Diffusion layer suspension is made by magnetic stirring, ultrasound mixing and by use of a ball-mill and the slurry is characterised by particle size measurements.

Innovative system designs for DMFC
Journal of Power Sources, 2006Abstract Bipolar designs for a direct methanol fuel cell (DMFC) with liquid electrolyte have been investigated, aiming at a reduction of methanol crossover. A “spacer” (separator) material has to be applied which is inert in a sulphuric acid/methanol surrounding.

Development of DMFC for Portable Application
2006This paper describes experimental results regarding manufacturing and electrochemical characterization of DMFCs with cathode catalyst layers based on supported and unsupported platinum catalysts. The cell performance in hydrogen and methanol solution, as different fuels, is compared and discussed in terms of electrochemical surface area (ESA) of the ...
