Methods for quantification of anode support microstructure

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Christian Monachon

Degradation observed on long term stack tests may be explained in part by microstructural changes of the electrodes. Particularly at the anode side, the coarsening of nickel particles will affect its performances. Increasing the metal particle size will fi ...
