Effect of Iron Species in Mesoporous Fe-N/C Catalysts with Different Shapes on Activity Towards Oxygen Reduction Reaction

Recent Developments of Metal-N-C Catalysts Toward Oxygen Reduction Reaction for Anion Exchange Membrane Fuel Cell: A Review

“…Since ORR kinetics in an alkaline media is faster than in an acidic media, a smaller amount and broader range of catalysts can be used for AEMFC than PEMFC [8,9]. In addition, due to the high pH, the components used in the fuel cell system also have an advantage in more affordable materials can be used because there is less concern about corrosion, and it was expected that non-precious metal catalysts could be applied [10][11][12].…”

High-corrosion-resistance mechanism of graphitized platelet-type carbon nanofibers in the OER in a concentrated alkaline electrolyte

“…Carbon is one of the key components in electrochemical energy conversion and storage systems, such as lithium-ion batteries, [1][2][3][4][5][6] electrochemical capacitors, [7][8][9][10][11][12][13][14][15] polymer electrolyte fuel cells (PEMFCs), [16][17][18][19][20][21][22][23] and metal-air secondary batteries (MABs). [24][25][26][27][28][29][30][31] However, carbon materials suffer from electrochemical oxidation; that is, carbon corrosion occurs in aqueous electrolytes at high anodic potentials, where many important electrochemical reactions, including the oxygen evolution reaction (OER), transpire.…”
