Identification of the active triple-phase boundary of a non-Pt catalyst layer in fuel cells. [PDF]
Sci Adv, 2022 The rational design of non-Pt oxygen reduction reaction (ORR) catalysts and catalyst layers in fuel cells is largely impeded by insufficient knowledge of triple-phase boundaries (TPBs) in the micropore and mesopore ranges. Here, we developed a size-sensitive molecular probe method to resolve the TPB of Fe/N/C catalyst layers in these size ranges.

Understanding the Role of Triple Phase Boundaries on Coating-Free Solid-State Cathodes. [PDF]
ACS Energy LettSulfide solid electrolytes have high ionic conductivities necessary to achieve high-rate solid-state cathodes at room temperature and low pressure. Cathode active materials generally require coatings to avoid deleterious oxidative decomposition reactions with the electrolyte. Coatings add cost and complexity to the manufacture.

Modelling the triple phase boundary length in infiltrated SOFC electrodes
International Journal of Hydrogen Energy, 2017 Abstract A model based on the principles of coordination number and percolation theory is proposed for calculating the triple phase boundary (TPB) lengths in the Solid Oxide Fuel Cell (SOFC) electrodes infiltrated with nano particles. The TPB length is a critical microstructural property that influences the cell performance. Empirical expressions for

New phase-field model for polycrystalline systems with anisotropic grain boundary properties
Materials & Design, 2022 In this paper, a new methodology is presented to inlude anisotropic grain boundary properties in a phase-field model. The new approach is thermodynamically consistent and gives accurate control of the inclination and misorientation of grain boundary ...
