| Outline of Final Research Achievements |
Operando experiments were carried out in which nickel was sputtered in a pattern onto yttria stabilized zirconia (YSZ) electrolyte substrates, and laser confocal microscopy images were acquired during power generation and electrolysis conditions. The effects of operating conditions such as fuel cell operation, electrolysis operation and reversible operation, as well as the effect of the electrolyte substrate, on the dynamic shape change of the nickel were observed and evaluated using laser and optical microscopy images.

本研究では，多孔体を模擬した微細凹凸つきパターン電極のoperando実験を行い，固体酸化物形セル多孔体燃料極中のニッケルの移動現象における，分極の向き（発電か電解か），電流密度の大きさ，電解質材料，幾何学形状等の影響を系統的に実験評価した．実際の多孔体電極では得られない，ダイナミックな直接観察に成功しているのは当グループだけである．
