氧化物燃料电池（SOFC）引起了研发社区的重大兴趣，作为替代的权力来源，已经进行了商业试验。在这些燃料电池中，电力是通过用氢气和氧作为燃料和氧化剂的电化学反应产生的。
Sealing these units is a critical technical issue that needs further work before they can be put into widespread commercial use. In particular the system chosen must exhibit good gas tightness, adhesion with adjoining components (electrolyte and connector), chemical compatibility, matching coefficient of thermal expansion and electrical insulation.
Recent work from researchers, Apichart Jinnapat, Sirithan Jiamsirilert and Sumittra Charojrochkul from Chulalongkorn University and Thailand's National Metals and Materials Technology Center, and published under AZojomo* (OARS)**, looked at ceramic adhesives and ceramic-glass composites. These materials were examined in terms of their chemical and thermal compatibilities with respect to potential use in SOFCs.
研究人员发现，所有经过测试的材料均表现出与YTTRIA稳定的氧欧洲杯足球竞彩化锆（YSZ）电解质和430条不锈钢互连系统的良好兼容性。在一般的玻璃陶瓷复合材料中，密封的材料比陶瓷粘合剂更好。欧洲杯足球竞彩经过热循环后，他们的密封特性也被发现优越。最有希望的密封材料是80/20 Pyrex玻璃/YSZ复合材料，其记录的泄漏速率低至2.41 x 10-4 cm3/min cm。
