Early planar cells were mostly electrolyte-supported. This requires a relatively thick electrolyte (>100 but typically around 200 μm, with both electrodes at about 50 μm) which leads to high resistance, requiring high-temperature operation. Sulzer Hexis and Mitsubishi Heavy Industries (MHI) are actively pursuing this technology and have scaled-up the technology into 1 and 15 kW systems, respectively. Power density at 0.7 V is reported to be about 140 mW/cm2 for the Sulzer stacks (57, 58, 59, 60, 61) and about 190 to 220 mW/cm2 for the MHI stacks (62, 63, 64, 65), both under commercially-relevant operating conditions. • Cathode-supported. This allows for a thinner electrolyte than electrolyte-supported cells, but mass transport limitations (high concentration polarization) and manufacturing challenges (it is difficult to achieve full density in a YSZ electrolyte without oversintering an LSM cathode) make this approach inferior to anode-supported thin-electrolyte cells. • Anode-Supported. Advances in manufacturing techniques have allowed the production of anode-supported cells (supporting anode of 0.5 to 1 mm thick) with thin electrolytes. Electrolyte thicknesses for such cells typically range from around 3 to 15 μm (thermomechanically, the limit in thickness is about 20 to 30 μm (the cathode remains around 50 μm thick), given the difference in thermal expansion between the anode and the 2 electrolyte). Such cells provide potential for very high power densities (up to 1.8 W/cm under laboratory conditions, and about 600 to 800 mW/cm2 under commercially-relevant conditions). 1 Where J = mA/cm2, for fuel composition of 67% H2/22% CO/11% H2O 7-31PDF Image | Fuel Cell Handbook (Seventh Edition)
