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
Highlights
Research focus has been to solid oxide fuel cells recently due to the increase in the petroleum fuel price and because of the call for environmental pollutions
In this paper studies on an intermediate temperature solid oxide fuel cell (IT-Solid Oxide Fuel Cells (SOFC)), which was fabricated by dry-pressing method has been conducted
The cell provided the maximum voltage of 840mV while operating at 560°C whereas the highest power density for this cell was recorded when it was operating at 680°C with an open cell voltage (OCV) of 675mV and a power density 195mW/cm2 at a current density of 700mA/cm2
Summary
Research focus has been to solid oxide fuel cells recently due to the increase in the petroleum fuel price and because of the call for environmental pollutions. Solid Oxide Fuel Cells (SOFC) are a part of the research due to its advantages in accepting wider range of gases as fuel and for that nature that it’s all solid based. The main drawback of the SOFCs is its high temperature operation in the range of 1000°C, resulting in material constraints for both electrode and cell construction. Recent focus is on reducing the operating temperature as it will give several advantages mainly giving a wider choice of low-cost and high performance materials with a higher stability which will reduce the degradation, increased freedom for structural design etc. The trend of research has been following the renewable and sustainable energy means with lower if not null impact on the environment
