Constructing a Multifunctional Interface between Membrane and Porous Transport Layer for Water Electrolyzers

Chang Liu et al.

Summary: This study evaluates the impact of different loadings of iridium on the investment costs of PEM water electrolyzers using titanium PTLs, finding that an Ir loading of 0.025 mg.cm(-2) as a protective layer is sufficient to achieve similar cell performance as higher Ir loadings. The Ir protective layer not only significantly reduces the Ohmic resistance, the largest part of the performance gain, but also shows promising oxygen evolution reaction activity, making it cost-effective as a catalyst layer.

Development of high-performance roll-to-roll-coated gas-diffusion-electrode-based fuel cells

Scott A. Mauger et al.

Summary: This study focuses on determining fabrication conditions to create high-performance roll-to-roll-coated gas-diffusion electrodes for proton-exchange-membrane fuel cells. It was found that using a higher drying rate can promote the formation of an ionomer-rich surface in the electrode. The R2R-coated GDEs have a higher surface ionomer concentration than spray-coated GDEs, eliminating the need for an additional ionomer overlayer and reducing processing steps and manufacturing costs.
