Durable Thin‐Film Porous Transport Electrodes for High Current Density PEM Water Electrolysis

Advanced Science, EarlyView.
Water electrolysis using porous transport electrodes with sputter‐deposited, ionomer‐free thin films of rutile IrO2 catalyst suppresses Ir dissolution by >10x over other forms of IrOx. The rutile IrO2 catalyst prepared by this readily scalable electrode synthesis method provides stable cell operation at 3 A cm−2 while using low Ir loading (0.4 mg Ir cm−

A Novel Metal Foam‐Supported Solid Oxide Fuel Cell With High Specific Power

Advanced Science, EarlyView.
Solid oxide fuel cells (SOFCs) employing metal foam supports with an ultrahigh porosity of 90% and average pore size of 100 µm are successfully fabricated. The metal foam architecture significantly enhances gas diffusion coefficients, effectively reducing concentration polarization while simultaneously decreasing areal mass.

High‐Efficiency CO2 Electrolysis Enabled by Interface‐Engineered Composite Electrolytes in Ni‐Based SOEC

Advanced Science, EarlyView.
This study addresses the critical issue of delamination between YSZ and GDC electrolytes in SOECs, which is caused by Thermal deformation disparity. A novel YSZ‐GDC composite interlayer, fabricated using a simple dip‐coating method, is introduced to solve this problem. This layer effectively suppresses delamination by mitigating thermal stress.
