Abstract
Description
Al(H2PO4)3+Al2O3→3AlPO4+3H2O(I)
加熱中、ガラスシール420のガラスは、ガラス転移点付近で軟化または溶融し、配置バリア層または中間バリア層に十分に浸透することで、固体酸化物燃料セルスタック400の作動の熱サイクル中に、適切な接着強度が中間バリア層の隣接層とガラスシール420との間で生じることができる。加えて、反応相が、中間バリア層のアルミニウム含有ホスフェートと、ガラスシール420の元素、例えばバリウム、ホウ素、イットリウム、カルシウム、ケイ素、亜鉛、マグネシウムとの間に形成され、それによってバリア層460およびガラスシール420との間の結合を強化することができる。
