在燃料电池研发的漫长历史中，电解质是三组分配置中的重要组成部分，因为它将阳极和阴极分开以实现燃料电池的功能。我们在这里报告了非电解质隔板燃料电池（NEFC）与基于电解质的燃料电池（EBFC）的比较。NEFC由基于混合离子和半导体的单或双组件组成，但没有电解质隔板。NEFC在550 °C时的最大功率密度为680 mW cm−2。NEFC表现出与传统EBFC相当的性能，在某些情况下甚至比传统EBFC更好。NEFC的设计、新材料功能和器件性能将有助于新型燃料电池的研发。
In the long-history of fuel cell R&D, the electrolyte is an essential part in a three-component configuration because it separates the anode and cathode to realize the fuel cell’s functions. We report here non-electrolyte separator fuel cells (NEFCs) compared with electrolyte based fuel cells (EBFCs). The NEFC consists of single- or dual-components based on mixed ionic and semi-conductors but with no electrolyte separator. A maximum power density of 680 mW cm−2 has been achieved by the NEFC at 550 °C. The NEFCs exhibit performances comparable to, and in some cases even better than, those of conventional EBFCs. The design of NEFCs, new material functionalities and device performances may contribute to new fuel cell R&D.
