Hello! I don't understand one easy moment in high temp solid oxydes fuel cells (SOFC): 1. Oxygen ions are moving always via solid electrolite ZrO2? SOFC without load and SOFC in short circuit modes. (High temp is default mean) 2. Electrolises process need electric energy and external current source must do EMF (electromotive force) anytime. SOFC use hidrogen chemical energy and oxydation process can be without current in output circuit. External load set optimal efficient point on output characteristics. Do I think right? 3. Is Magnet field around solid electrolite always? When load exchange from 0 to short circuit. How magnet field do depend with load? 4. Perhaps do EMF about 1V block ions move in solid electrolite for load 0 and feild is 0 to? Thank you for any help!
