Operation Principle of Metal Supported - Solid Oxide Fuel Cell (MS-SOFC)
-
3 layer structure of anode, ceramic electrolyte, and cathode
-
Oxygen at the cathode receives electrons and becomes oxide-ion
-
Oxide-ion pass through the ceramic electrolyte and move to the anode
-
Hydrogen and oxide-ion react at the anode to form water and release electrons
-
The electrons move through the external circuit and an electric current flows
Advantages & Features
A Simple Stack Design
-
Fast start-up and thermal cycling
-
The mechanical properties are significantly improved by supporting with metal (stainless)
-
Expected to lower the cost
Ultrathin Electrolyte Layer of 4 μm
-
High power generation performance of over 0.7 W/㎠ in the medium temperature range of 600℃ to 750℃.
-
The thickness of the electrolyte has been reduced to 4 μm by utilizing thin-layer technology of MLCC.
Customizable up to a Maximum Size of □100 mm
Less micro-cracks in electrolyte layer and loss due to gas leak is lower than 1.1%
