- Description
- An increased interest in using hydrocarbons in solid oxide fuel cells for the production of power has led to research into operation on synthesis (syn) gas, a mixture of hydrogen and carbon monoxide. Hydrocarbons are typically reformed, either internally or in an external reformer prior to the fuel cell, producing syngas with various H₂:CO ratios depending on the hydrobarbon used. This paper examines the effect of varying the H₂:CO ratio with respect to C₁ to C₄ steam reforming reactions and additionally a mixture containing a higher ratio of carbon monoxide. It was found that there was no significant relationship between cell performance and H₂:CO ratio. For low flow rates, however, the high carbon monoxide concentration resulted in a significant decease in cell performance. It was determined that this was caused by reversible carbon deposition as opposed to a decrease in carbon monoxide reactivity.
