PEM Fuel Cells: Status and Challenges for Commercial Stationary Power Applications

摘要

The past decade has seen tremendous advances in proton exchange membrane fuel cell (PEMFC) technology. However, there remain many challenges to bring commercially viable stationary PEMFC products to the market. This review, from a manufacturer's perspective, focuses on system reliability and materials compatibility and their strong impact on stack life and, overall system durability. Statistical analysis is based on field data from more than 600 stationary PEMFC systems for both continuous and back- up power applications. Sealing materials and coolants are used to illustrate the approaches taken to evaluate materials compatibility studies.
