The setup is shown below. The novel … Read More

Multilayer CO2 Electrolyzer Stack Using Reinforced Sustainion® AEM

An ACS Energy Paper presents a zero gap electrolyzer cell and stack, which continuously converts gas phase CO2 to products without using any liquid catholyte. This is the first report of a multi layer CO2 electrolyzer stack for scaling up the electrolysis process. The stack contained up to three electrolyzer layers (having 61 cm2 /stack active area). However, a PTFE … Read More

Sustainion® XA-9 ionomer reduces parasitic ORR to generate C2 Products from Fuel Gas

Parasitic ORR is of particular concern since the thermodynamic voltage of ORR is more than 1 V more positive than CO2RR, and thus could displace CO2RR activity. Researchers at University of Toronto published a journal article titled ‘Oxygen-tolerant electroproduction of C2 products from simulated flue gas’ which featured in the themed collection of Energy and Environmental Science HOT Articles. To … Read More
