The aim of the project ComDeWE is to design optimal wholly hydrocarbon proton exchange membrane electrolysis (PEMWE) cells with novel supported electrocatalyst by taking advantage of the numerical multi-scale modelling tools at the University of Alberta (U Alberta), and in-situ and ex-situ fabrication and characterization tools at the University of Freiburg (U Freiburg), German Aerospace Center (DLR), Simon Fraser University (SFU) and the U Alberta. The project will focus on leveraging five technologies developed by the applicants to create a proof-of-concept wholly hydrocarbon PEMWE. These are: a) hydrocarbon based membrane expertise from Dr. Holdcroft at SFU and catalyst layer fabrication techniques developed at SFU, U Freiburg and U Alberta; b) novel supported electrocatalysts from DLR; c) graded-electrode enabling inkjet printing and ultrasonic spray electrode fabrication tools at U Alberta, U Freiburg and SFU; d) segmented PEMWE hardware developed at DLR to study local current density and temperature distribution; and, e) the validation and use of micro- and macro-scale numerical simulation tools developed at U Alberta and DLR for discovering the optimal membrane and electrode thickness as well as electrode composition. To date, all research related to the integration of hydrocarbon-based materials to CCMs for PEMWE has been driven by tedious experimental trial-and-error. It is hypothesized that, because of the very different characteristics of these membranes (e.g., higher proton conductivity, reduced gas crossover and increased swelling), a more holistic approach to their analysis and design is required. Taking advantage of novel supported catalyst also requires a more holistic approach to electrode design. This proposal leverages the long history of research activities and investments in state-of-the-art laboratory equipment at these facilities as well as previous collaborations between SFU, UFreiburg, UAlberta and DLR. The international collaboration addresses the challenges of developing suitable materials for PEM electrolyzers.
