摘 要: 燃料電池(SOFC)是一種能夠?qū)⒒瘜W(xué)能直接轉(zhuǎn)化為電能的清潔能源轉(zhuǎn)換裝置，根據(jù)電解質(zhì)材料傳導(dǎo)離子的不同，可將電解質(zhì)分為氧離子導(dǎo)體型和質(zhì)子導(dǎo)體型兩種，因而SOFC可分為氧離子導(dǎo)體SOFC (O-SOFC)和質(zhì)子導(dǎo)體 SOFC(H-SOFC)。傳統(tǒng)的高溫O-SOFC已經(jīng)發(fā)展多年，制備技術(shù)成熟，在高溫下性能優(yōu)越，但是隨著電池工作條件往中低溫發(fā)展，質(zhì)子傳導(dǎo)型固體氧化物燃料電池(H-SOFC)具有更低的工作溫度、更小的活化能值和更高的電池效率，因而得到了研究者的廣泛關(guān)注和發(fā)展。本文主要介紹了質(zhì)子傳導(dǎo)型固體氧化物燃料電池的結(jié)構(gòu)、工作原理，并在此基礎(chǔ)上著重分析了近年來質(zhì)子傳導(dǎo)型燃料電池的材料包括單相陰極、復(fù)合陰極、BaCeO3和BaZrO3形成的固溶體電解質(zhì)、陽極改性以及性能優(yōu)化等主要研究方向和發(fā)展趨勢。分析了目前陽極和電解質(zhì)種類少、陰極催化活性低的問題。

Abstract:Solid oxide fuel cell (SOFC) is a clean energy conversion device that can directly convert chemical energy into electrical energy. According to the difference in ions conducted by the electrolyte material, the electrolyte can be divided into an oxygen ion conductor type and a proton conductor type. Therefore, SOFC can be divided into two types: oxygen ion conductor SOFC (O-SOFC) and proton conductor SOFC (H-SOFC). The traditional high-temperature O-SOFC has been developed for many years, the preparation technology is mature, and the performance is superior at high temperatures. However, as the battery working conditions develop towards medium and low temperatures, the proton conduction solid oxide fuel cell (H-SOFC) has a lower operating temperature, a smaller activation energy value and a higher battery efficiency, which has attracted wide attention and development of researchers. This article mainly introduced the structure and working principle of proton conduction solid oxide fuel cell, and on this basis, focused on analyzing the materials of proton conduction fuel cell in recent years, including single-phase cathode, composite cathode, solid solution electrolyte formed by BaCeO3 and BaZrO3;The main research direction and development trend of anode modification and performance optimization. The problems of the current few types of anodes and electrolytes and the low catalytic activity of the cathodes were analyzed.
Key words: solid oxide fuel cell; proton conductivity type; cathode; medium and low temperature
