摘要: Fuel cell technology, a core component in hydrogen-based energy economy, has the advantages of high conversion efficiency, low pollution, and no dependency on depleting fossil resources. Significant progress been made state-of-the-art materials, design, fabrication, however, widespread commercialization most fuel cells is still limited by issues such as cost durability [1–4]. Mathematical models are effective tools understanding optimization various transport electrochemical processes, leading to reduction improved performance durability. The purpose this chapter summarize current status fundamental for that have actively studied past decade
