| 摘要 |
<p>The present invention has an ion-conducting layer (11), and a first electrode (21) and a second electrode (22) respectively formed on front and reverse surfaces of the ion-conducting layer (11). The first electrode (21) is formed from a metal that is capable of feeding metal ions to the ion-conducting layer (11), while the second electrode (22) is formed from a metal that does not feed metal ions to the ion-conducting layer (11). The ion-conducting layer (11) is formed from a compound containing oxygen or a metal oxide, and has an oxygen composition ratio that is less than a stoichiometric amount.</p> |
