Investigation into the effects of sulfur on syngas reforming inside a solid oxide fuel cell
The electrochemical performance and long-term durability of a solid oxide fuel cell have been evaluated with a simulated coal syngas containing 2 ppm H2S as fuel. The resulting impedance spectra indicate that no observable power loss is caused by the addition of 2 ppm H sub(2)S, and the cell shows s...

| description | The electrochemical performance and long-term durability of a solid oxide fuel cell have been evaluated with a simulated coal syngas containing 2 ppm H2S as fuel. The resulting impedance spectra indicate that no observable power loss is caused by the addition of 2 ppm H sub(2)S, and the cell shows stability of nearly 500 h at 0.625 A cm super(-2). The composition of mixed gas is analyzed both at a current load of 0.625 A cm super(-2) and open circuit state. Hydrogen and carbon monoxide are directly consumed as fuels at the anode side, whereas methane stays unchanged during the operation. It seems the internal carbohydrate reforming and impurity poisoning interacts and weakens the poisoning effects. The oxidation of H sub(2) and the water gas shift reaction take advantages over methane reforming at the cell operational conditions. |
