A microwave sintering technique is reported for fabricating co-sintered proton-conducting solid oxide fuel cells. With this method, high-quality ceramic electrolyte membranes can be prepared at 1100 °C, thus enabling the fabrication of entire cells in a single step. The microwave sintering method not only enhances electrolyte densification but also improves the cathode/electrolyte interface, which is critical for improving fuel cell performance. The power output of the co-sintered cell prepared under the microwave conditions (up to 449 mW cm⁻² at 700 °C) was significantly higher than that of the cell fabricated using the traditional co-sintering method (approximately 292 mW cm⁻² at the same temperature). Electrochemical analysis revealed that the enhanced electrolyte density and the improved cathode/electrolyte interface achieved by using the microwave sintering technique decrease both the ohmic resistance and the polarisation resistance of the cell, leading to good fuel cell performance.

据报道，微波烧结技术用于制造共烧结的质子传导固体氧化物燃料电池。使用这种方法，可以在1100°C的温度下制备高质量的陶瓷电解质膜，从而可以在一个步骤中制造整个电池。微波烧结法不仅增强了电解质的致密性，而且改善了阴极/电解质的界面，这对于提高燃料电池的性能至关重要。在微波条件下制备的共烧结电池的功率输出（在700°C时高达449 mW cm ^-2）显着高于使用传统共烧结方法制造的电池（约292 mW cm ^-2）在相同的温度下）。电化学分析表明，使用微波烧结技术可提高电解质密度并改善阴极/电解质界面，从而降低电池的欧姆电阻和极化电阻，从而获得良好的燃料电池性能。
