The sluggish rate of the oxygen reduction reaction (ORR) in proton exchange membrane
(PEM) fuel cells has been a major challenge. Significantly increasing efforts have been …

Stricter requirements for MEA structure have to be met in order to realize the rapid
commercialization and marketization of polymer electrolyte membrane fuel cell (PEMFC) …

Abstract One-dimensional (1D) Pt-based electrocatalysts demonstrate outstanding catalytic
activities and stability toward the oxygen reduction reaction (ORR). Advances in three …

For polymer electrolyte membrane fuel cells (PEMFCs), the importance of durability is widely
recognized, but less attention has been paid to the role of ionomers. In this study, the …

The catalyst layer (CL) is the only electrochemical reaction site in proton exchange
membrane fuel cells (PEMFCs), decisive in their performance. Herein, a mild and simplified …

In this work, novel Nafion-free membranes composed of zirconium silicate, lignin, and ionic
liquids supported on polytetrafluoroethylene have been synthesized for high-temperature …

The commercialization of proton exchange membrane fuel cells (PEMFCs) is closer to the
reality than ever before. Electrode interface development can bring a boost to the last few …

A gradient Pt nanowire (Pt-NW) cathode with a promoted mass transfer and Pt utilization
was developed by decal transfer method. The relationships of Pt loading and ionomer …

Conventional catalyst layer with a smooth surface exists the larger area of “catalytic dead
zone” and reduces the utilization of catalyst. Based on this, a novel catalyst layer structure …

Catalyst layer (CL) is the key factor of affecting the performance of proton exchange
membrane fuel cells (PEMFCs). Herein, a facile and universal strategy is proposed to in situ …
