Performance Study On An Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFT) Fabricated By Dry Pressing Method

Abstract

An intermediate temperature solid oxide fuel cell (IT-SOFC) has been developed by using the dry pressing method. Widely studied materials were used for anode and cathode and SDC based electrolyte was used in this study. The cells were fabricated by dry-pressed at different pressures using a die without any binding material, a known amount of three electrode materials in powder form were pressed together and a nickel mesh was used as current collector. The test area of the fabricated cells was 0.785 cm². The experiments were conducted using H2 as fuel and compressed air as oxidant. The cells were tested under different operating temperatures with varying fabrication parameters. The fabricated cells recorded an open cell voltage (OCV) of 765mV while operating at 560°C. The maximum current density obtained was 726mA/cm² and with a power density of 193mW/cm²
