Analytical-based simulation approach for an anion exchange membrane fuel cell

Recent progress in understanding the catalyst layer in anion exchange membrane electrolyzers – durability, utilization, and integration

“…In comparison, PEMWE systems utilize flow fields made of Ti due to its acidic stability. Pt or Au protective coatings are 65 often used to help with longevity and minimize contact resistances, 55 although the use of PGM or noble-metal-based materials can contribute to cost concerns. Ti oxidation (i.e., to TiO 2 ) can lead to increased contact resistances, which can result in a decrease in overall cell performance.…”

“…In this review, the catalyst layer specifically refers to (1) the catalyst particles themselves, (2) the anion-conducting polymer (referred to as the ionomer) dispersed with the catalyst particles, (3) their interface with the porous transport layer, and (4) their interface with the anion exchange membrane (shown schematically in Fig. 2b and as a cross-sectional SEM image from JM Mora et al 65 in Fig. 2c).…”
