Abstract

Szilárd halmazállapotú ionos eszköz magában foglal egy sűrűelektrolitot, amely két porózus elektróda közé van helyezve. Az egyikkiviteli változatban az eszköz anód támogatású, és a katód egyporózus, háromfázisú szilárd szerkezetből van kiképezve, amelynek egytöbbségében 14 elektrokatalitikus részecskékből állóelektrokatalitikus fázisa és egy többségében 16 ionvezetőrészecskékből álló ionvezető fázisa van. Az elektrokatalitikusrészecskék közép- vagy átlagmérete nagyobb, mint az ionvezetőrészecskék közép- vagy átlagmérete. Az eszköz továbbá tartalmaz egynagy hatótávolságú elektronikusan vezető réteget lantán-kobaltból vagymás elektronikusan vezető anyagból. Ó
