Outline of Final Research Achievements

A hydrogen permeable membrane fuel cells (HMFC) were fabricated by using BaZr0.1Ce0.7Y0.1Yb0.1O2.9 (BZCYYb1711) and highly-oxygen deficient BaZr0.1Ce0.5Y0.1Yb0.3O2.8 (BZCYYb1513) for the proton-conducting electrolyte. BZCYYb1711 electrolyte gained 0.08 H2O mole fraction while highly-oxygen deficient BZCYYb1513. gained 0.17 via defect-water association. Furthermore, the HMFC using highly-oxygen deficient BZCYYb1513 exhibited an open circuit voltage of 1.15 V and an output of 0.5 A cm-2@0.7 V at 400°C, while the cell using the BZCYYb1711 had an open circuit voltage of 0.95 V and an output of 0.25 A cm-2@0.7 V. These demonstrate the enhanced proton-pumping effect on HMFC with highly-oxygen deficient electrolyte.

Academic Significance and Societal Importance of the Research Achievements

本研究の目的はであるHMFCは、アノード側がデッドエンド構造、即ちアノード排気ガスが基本的に必要無い。従って水素燃料を無駄にすることがなく、水素利用率100%の燃料電池として期待できる。一方で従来のHMFCは貴金属Pdを大量に必要としたが、本研究では作動温度を300℃程度まで低減することに成功したため、V等の遷移金属水素透過膜を利用したセルを開発することができた。従って大型船舶や定置型電源に利用可能な高効率中温作動型燃料電池の道筋をつけた。
