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.

ComDeWE项目的目的是利用阿尔伯塔大学的数值多尺度建模工具，设计具有新型负载型电催化剂的最佳全烃质子交换膜电解（PEMWE）电池（U阿尔伯塔），以及弗赖堡大学的原位和非原位制造和表征工具（U弗赖堡）、德国航空航天中心（DLR）、西蒙弗雷泽大学（SFU）和U阿尔伯塔。该项目将侧重于利用申请人开发的五项技术来创建一个概念验证的全碳氢化合物PEMWE。这些是：a）来自SFU的Holdcroft博士的碳氢化合物膜专业知识和SFU、U弗赖堡和U阿尔伯塔开发的催化剂层制造技术; B）来自DLR的新型负载型电催化剂; c）在U阿尔伯塔、U弗赖堡和SFU的梯度电极喷墨打印和超声喷涂电极制造工具; d）在DLR开发的分段PEMWE硬件，用于研究局部电流密度和温度分布;以及，e）验证和使用在U阿尔伯塔和DLR开发的微观和宏观尺度数值模拟工具，以发现最佳膜和电极厚度以及电极成分。迄今为止，所有与将碳氢化合物基材料整合到PEMWE的CCM相关的研究都是由繁琐的实验性试错驱动的。假设由于这些膜的非常不同的特性（例如，更高的质子传导率、减少的气体交叉和增加的膨胀），需要更全面的方法来分析和设计它们。利用新型负载型催化剂还需要更全面的电极设计方法。该提案利用了这些设施的研究活动和最先进的实验室设备投资的悠久历史，以及SFU，UFreiburg，UAlberta和DLR之间的先前合作。国际合作解决了为PEM电解槽开发合适材料的挑战。
