A fuel cell catalyst layer capable of improving the below-freezing start performance of a fuel cell is provided. A catalyst layer for a fuel cell, comprising a carrier supporting a catalyst, an ionomer having proton conductivity, and a cellulose-based nanofiber having an average fiber diameter ...
In summary, we elaborated on an approach that provides access to quantitative, three-dimensional data at nanometre resolution, allowing a detailed observation of the proton-exchange membrane fuel cell catalyst layer structure with all of its components. It was demonstrated that—although not completely...
The polymeric ionomer plays a vital role in PEM fuel cell device technology, not simply as the membrane that transports protons and water from one electrode to another but as the binder and transport medium responsible for electrochemical activity within the catalyst layer. This perspective examines ...
During imaging using conventional electron microscopy, delicate catalyst layer samples often become damaged by electron beams, causing materials to shrink or deform. By carrying out the imaging in-situ at cryo-temperatures, Tileli and her team were able to preserve most of the catalyst layer's mor...
