On the Nature of Mixed Potential in a DMFC [PDF]
Journal of The Electrochemical Society, 2005 A ID + ID model of a direct methanol fuel cell (DMFC) is developed. Analytical solution for the case of equal oxygen and methanol stoichiometries X is obtained. The model predicts a new effect: formation of a narrow zone of local current (bridge), which "short-circuits" cell electrodes at vanishingly small current in the load.

Numerical investigation of methanol crossover through the membrane in a direct methanol fuel cell [PDF]
Hydrogen, Fuel Cell & Energy Storage, 2018 A two-dimensional, single-phase, isothermal model has been developed for a direct methanol fuel cell (DMFC). The model considers the anode and cathode electrochemical equations, continuity, momentum and species transport in the entire fuel cell.

Facile solvothermal synthesis of Pt-Cu nanocatalyst with improved electrocatalytic activity toward methanol oxidation [PDF]
Journal of the Serbian Chemical Society, 2019 A binary metal nanocatalyst of platinum and copper was synthesized using a facile solvothermal process (polyol method). The synthesized catalyst was characterized using energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD) and transmission ...

Heat and Mass Balance Analysis of 130-W Active-type Direct-methanol Fuel Cell
Electrochemistry, 2022 A “heat- and mass-balance analysis” for a direct-methanol fuel cell (DMFC) system, accounting for actual experimental data and the heat- and mass transfer of the DMFC, is proposed to facilitate the usage of general spreadsheet software.
