His work focuses on enhancing the efficiency and functionality of polymer membranes used in various electrochemical applications.

Latest Patents

Gubler's latest patents include a method for preparing a polymer membrane for a polymer electrolyte water electrolyser. This innovative method involves creating an ionomer of an ion exchange membrane with a recombination catalyst to prevent gas crossover of species, such as hydrogen and oxygen, between anodic and cathodic cell compartments. The ionomer is a proton or anion exchange polymer, and the recombination catalyst is provided in ionic form within a liquid metal salt solution. The process includes immersing the ion exchange membrane into the solution to facilitate the exchange of ionic ionomer ports with the ionic form of the catalyst. The membrane is then assembled in the electrochemical cell, where the ionic form of the catalyst is partially reduced to metallic form by allowing hydrogen to permeate through the ionomer.

Another significant patent involves a method for removing non-proton cationic impurities from an electrochemical cell. This method effectively eliminates impurities from the ionomer in a proton exchange membrane and from the catalyst layers on both the anode and cathode sides. The process includes providing supply paths for anode and cathode feeds to the ionomer, and using a regenerating fluid with acidic pH to achieve ion exchange, thereby removing impurities without increasing the risk of corrosion or interrupting the electrochemical process.
