Primary Study on Solid Oxide Fuel Cells

Abstract

Abstract: A trial tubular SOFC system was fabricated. The electrical performance of this SOFC was evaluated at temperatures of 500 to 950℃. H₂ and CH₄ were used as the fuels and air as the oxidant
gas. The internal resistance, output current and output power of this SOFC were measured. When H₂ and CH₄ were imported into the SOFC system
at 950℃, the open circuit voltages were 0.98V and 1.05V, maximum output current densities were 19.6mA/cm² and 16.4mA/cm², the maximum output power was 30.0mW and 24.4mW, respectively. The endurance test was conducted over 145h, but this SOFC system showed no significant degradation.

Key words: solid oxide fuel cell, electrical performance, internal resistance
