On the influence of the anodic porous transport layer on PEM electrolysis performance at high current densities

Advances in Oxygen Evolution Electrocatalysts for Proton Exchange Membrane Water Electrolyzers

“…Currently, the operating temperature used in most literature is 80 °C, because a higher temperature (>100 °C) places higher demands on the components of the device such as membrane dehydration and requires higher pressure of the device. [263] In industry, increased cost from high temperature should be evaluated against the economic benefits of performance optimization to operate under optimal conditions. Scott et al studied the effects of pressure on the performance of PEMWE at high temperature.…”

A high-performance, durable and low-cost proton exchange membrane electrolyser with stainless steel components

“…Efficient gas/water management has a high impact on the cell performance due to the reduction in mass transport losses. [5][6][7] On the cathode side, carbon paper is a stateof-the-art PTL material, which is often used in PEM fuel cells (FC). 8 On the anode side, titanium is widely used for PTLs since titanium can withstand the harsh conditions of a highly concentrated O 2 environment and elevated cell potentials (42 V).…”

Porous Transport Layers for Proton Exchange Membrane Electrolysis Under Extreme Conditions of Current Density, Temperature, and Pressure

“…The PTL on the anode, which is made of Ti, is an important key component, which needs to ensure effective media transport, specifically water transport from the flow field of the BBP to the electrodes and gas removal. It is well known that gas/water management strongly influences cell performance [ 20–22 ] and mass transport losses (MTL) must be kept low. Therefore, this phenomenon becomes more relevant with increasing the applied electrical current, as the production rates of the gases increase.…”
