The 3D secrets of fuel cell catalyst layers

Nature Catalysis volume 6, pages 378–380 (2023)Cite this article

Subjects

Proton exchange membrane fuel cell catalyst layers (CLs) have complex structures that largely determine their performance and durability. Their three-dimensional morphology and component spatial distribution is still poorly understood. This comprehensive work reports one of the first cryogenic transmission electron tomography reconstructions of a full commercial CL section, including challenging-to-image ionomer distribution.
