Description
(1)多孔質支持体の表面に水素透過膜および隔離部材を形成した水素分離部材を固定部材で固定した水素分離部を有する水素分離装置であって、水素分離部材と固定部材との接合部において多孔質支持体の表面に形成した隔離部材と固定部材とがろう材により接合されており、隔離部材と多孔質支持体とが直接接合されており、ろう材と水素透過膜とは隔離部材により隔離されている水素分離装置。
(2)隔離部材のうち、多孔質支持体との接合部がガラスまたはセラミックスの緻密層で形成されている(1)に記載の水素分離装置。
(3)隔離部材のうち、ろう材との接合部がガラスまたはセラミックスと、金属との複合材料層で形成されている(2)に記載の水素分離装置。
(4)固定部材を形成する材料が、金属である(1)〜(3)のいずれかひとつに記載の水素分離装置。
(5)(1)〜(4)のいずれかひとつに記載した水素分離装置における多孔質支持体に水素製造触媒の機能を付与して触媒兼多孔質支持体とした水素製造装置。
但し、この水素分離装置の接合部付近の詳細は図3に示す構造となっている。まず、100質量部の純水にNiO粉末(平均粒径0.5μm)60質量部と、イットリア8モル%を固溶したジルコニア(以下、単に「8YSZ」と称する場合がある。)粉末(平均粒径0.5μm)40質量部とを混合し、さらにバインダ(ワックス)5質量部と、造孔剤として人造黒鉛粉20質量部を配合して混練してスラリーとした。均一に混練したスラリーをスプレードライによって造粒した。得られた造粒粉を、一端が開口し他端が閉塞した中空の円筒状に加圧成形し、支持体3のグリーンを作製した。この多孔質支持体3のグリーンの開口部付近の外側表面に、エタノール300質量部中に8YSZ粉末100質量部とアクリル系バインダ5質量部と分散剤1質量部を混合したスラリーにより、ディップコート、乾燥を数回繰りかえして緻密層6aのグリーンを形成した。さらにこの緻密層6aのグリーンの上に、エタノール300質量部中にNiO粉末60質量部、8YSZ粉末40質量部、人造黒鉛粉20質量部、アクリル系バインダ5質量部および分散剤1質量部を混合したスラリーにより、ディップコート、乾燥を数回繰りかえして複合材料層6bのグリーンを形成した。なお、塗布量は、焼成後に緻密層6aおよび複合材料層6bの膜厚が、それぞれ10μm、2μmとなるように調整した。この隔離部材6のグリーンを形成した多孔質支持体3のグリーンを500℃20時間脱脂処理した後、1400℃で1時間焼成して隔離部材6を備えた多孔質支持体3を作製した。この多孔質支持体3は、およそ外径9mm、内径7mm、長さ100mmの試験管状の形状である。隔離部材である緻密層6aおよび複合材料層6bは、多孔質支持体3の開口部付近の外周表面に長さ10mm、厚さ10μmおよび2μmで形成されていた。
