ELECTROCHEMICAL CELL COMPRISING A COMPOSITE PROTON EXCHANGE MEMBRANES WITH INTERLAYER STRUCTURE

Resumen de: EP4818367A1

The development of more cost-effective and efficient proton exchange membrane (PEM) water electrolysis cells requires the use of thinner membranes with extended lifetimes and reduced gas crossover. The inventive approach to address these challenges involves the incorporation of radical scavengers to mitigate radical-induced ionomer degradation, along with gas recombination catalysts to promote the conversion of crossover hydrogen and oxygen to water inside the PEM. Each of the two catalyst types has its distinct chemical reaction characteristics, to which the design of the composite membrane is tailored through rational considerations. In various embodiments of the present invention, the positioning effects of Ce_0.5Zr_0.5O₂ and Pt interlayers in composite membranes for their respective roles in radical scavenging and gas recombination were investigated. Results reveal that placing a radical scavenger interlayer near the cathode notably reduces the ionomer degradation rate, compared to its placement near the anode, evidenced by a 61% ± 7% reduction in fluoride release rate. This is likely due to reactive oxygen species in the cell being predominantly generated at the cathode, which is closer to the radical scavenger interlayer in the former case. The Ce content in cerium-zirconium oxide was further optimized using an ex-situ Fenton test, with Ce_0.25Zr_0.75O₂ demonstrating the highest radical scavenging activity.
