Abstract
A solid electrolyte cell having .beta.-alumina as a solid electrolyte is disclosed. In this cell, positive active material and negative active material are opposed to each other with an intervening .beta.-alumina solid electrolyte layer therebetween. The utilization of the positive active material is increased in order to prolong the life of the heightened cell by mixing a conductive metal powder into the positive active material or by inserting an electrical conductor into the positive active material which is inert to the active material. The conductor is conductively connected to the electrode terminal of the cell.
