“…Other methanol tolerant catalysts have been found in iron porphyrine-type materials supported on high surface area carbon [133,134]. These catalysts were tested in fuel cell conditions and it was found that no deterioration of the electrode performance could be seen when utilising methanol in the cell.…”

“…Radyushkina et al [97] Gupta et al [100] reported that heat-treated (FeTMPP) 2 O, Cl-FeTMPP and Cl-FeOEP (OEP = octaethylporphyrin) supported on high-area carbons, e.g., deashed and un-deashed RB carbon (Calgon) and Black Pearls (BP) 2000 (Cabot) exhibit stable and very high oxygen reduction rates. The performances are comparable to supported platinum (E-Tek), when tested in 85% H 3 PO 4 -equilibrated Nafion 117 membrane at 125 °C and hydrated-Nafion membrane at 60 °C in a minifuel cell.…”

This review covers the electrocatalytic activities, the corresponding influence factors and the synthesis methods of nonprecious‐metal electrocatalysts towards oxygen‐reduction reaction (ORR) for fuel‐cell systems. In particular, the chalcogenides and the macrocycles containing Co or Fe metals have been focused upon. Due to the scarcity of Pt metal, the Co‐ and Fe‐based chalcogenides are potentially interesting substitutes of Pt although they still show lower catalytic activities for ORR and lower electrochemical and chemical stability in the present fuel‐cell electrolytes. Compared to Pt electrocatalysts, the Co‐ and Fe‐based macrocycles, such as TMPP, TPP, Pc and TAA, are among the most promising substitutes for Pt because of their comparable catalytic activities towards ORR and the higher insensitivity to methanol (in direct methanol fuel cells – DMFC) although they still have some drawbacks, namely lower stability and shorter durability. Novel catalyst synthesis methods, modification techniques of catalysts as well as supporting substrates are expected to be developed in the future to satisfy the requirements of commercial fuel cells.

“…[114,115] Other methanol-tolerant catalysts have been found in iron ± porphyrin materials supported on high surface area carbon. [116,117] These catalysts were tested under fuel cell conditions and it was found that no deterioration of the electrode performance could be seen when methanol was utilised in the cell. These catalysts were also combined with a new cell concept, whereby the anode and cathode reside in the same compartment.…”
