Effects of porous and dense electrode structures of membrane electrode assembly on durability of direct methanol fuel cells

Synthesis and characterization of platinum supported on surface-modified ordered mesoporous carbons by self-assembly and their electrocatalytic performance towards oxygen reduction reaction

“…However, Pt/OMC-H 2 SO 4 had the n value of 1.6, which was also responsible for the worst ORR activity among all electrocatalysts. It is well-known that two- electron reductions during ORR lead to production of hydrogen peroxide radicals which attack the carbon supports as well as the proton exchange membrane (PEM) electrolytes, resulting in an undesirable degradation of the membrane-electrolyteassembly (MEA) of the fuel cells [31].…”

Regeneration of the power performance of cathodes affected by biofouling

“…Although the presence of a biofilm on the outer layer of the cathode can be inspected at a macroscopic scale, it is important to determine whether this biofilm may cause the power drop in MFCs. In the field of conventional fuel cells science, R&D has led to determining the role of cathode deterioration on power performance and appropriate strategies are currently being developed to address this problem [29] , [30] .…”

A Ti-coated nano-SiC supported platinum electrocatalyst for improved activity and durability in direct methanol fuel cells

“…This susceptibility can directly inuence the durability of Pt electrocatalysts. [15][16][17][18][19][20] For these reasons, more advanced supporting materials should be developed to meet the requirements for the commercialization of DMFCs. [21][22][23][24] Great efforts have been made during the last decade to investigate the non-carbon support materials, including oxides, carbides, and nitrides.…”
