Graphene carbon black as catalyst support: The influences of iron phthalocyanine loading and carbon black additive amount on the power generation performance of direct glucose fuel cell

Shuai Wang et al.

Summary: Efficient oxygen reduction reaction (ORR) species accessibility to catalyst surface is crucial for catalysis, and can be achieved by engineering the structure and morphology of catalyst supports. The 3D rGO/CB/rGO network, as a unique catalyst-loading platform, demonstrates efficient transport of ORR-species to each catalytic site, leading to significant improvements in cell performance. The synergistic effect of rGO and carbon black, as well as pi-pi interaction between rGO and TFePc, play important roles in achieving a high power density of 0.86 mWcm(-2) for TFePc/rGO/CB-3 in practical cells.

Challenges in applying highly active Pt-based nanostructured catalysts for oxygen reduction reactions to fuel cell vehicles

Kensaku Kodama et al.

Summary: Progress has been made in the development of Pt-based nanocatalysts for the oxygen reduction reaction over the past 30 years, with some now in commercial production for PEFCs. However, further improvements in catalytic activity are needed. State-of-the-art catalysts have potential to enhance energy conversion efficiencies and reduce platinum usage in PEFCs, but technical challenges remain for their application in fuel cell vehicles, such as high power density, practical durability, and efficiency.

Structurally Disordered Phosphorus-Doped Pt as a Highly Active Electrocatalyst for an Oxygen Reduction Reaction

Bang-An Lu et al.

Summary: The study introduces a phosphorus-doping strategy to significantly enhance the ORR performance of Pt catalysts, while also improving their durability. By introducing phosphorus into the near-surface of commercial Pt/C catalysts using a surfactant-free method, the ORR mass activity was enhanced by 7 times and showed only 14% loss after 10,000 potential cycles, indicating a promising approach for proton-exchange membrane fuel cell applications.

Advancements in cathode catalyst and cathode layer design for proton exchange membrane fuel cells

Yanyan Sun et al.

Summary: The high platinum loadings at the cathodes of proton exchange membrane fuel cells significantly increase the cost of these clean energy conversion devices. Recent developments focus on low- and non-platinum-based cathode catalysts and catalyst layers to address this issue. Advances in nanotechnologies and material sciences have led to the discovery of promising materials, including platinum-based alloys and platinum-group-metal-free catalysts, for more cost-effective solutions in the future.
