  • Reactivity of methane increases gradually with the increase of temperature, which can affect the EMF and OCV of SOFC. When the humidified mixture of nitrogen and methane is used as the fuel, the EMF and OCV of SOFC increase gradually with the increase of temperature.

methane SOFC stack is possible. • LSCF-GDC is a potential solution for low-T low polarization cathode. Title: Microsoft PowerPoint - JiangLiu.SECA Review 2002.ppt Author: ford Created Date:

Measurements of direct-methane SOFC stability showed that at lower temperatures, ≤ 700 °C, stable operation without coking occurred over a wide range of current densities. At higher temperatures, increasingly large currents were required to avoid coking and cell failure. In electrochemical impedance spectra, two electrode arcs were observed ...

The results suggest that coke-free SOFC operation was achieved due to kinetic limitations on the methane cracking reaction, particularly at low temperature. It is suggested that oxidation of hydrogen, produced by methane reforming by reaction products within the anode, is an important electrochemical reaction; the resulting steam helps remove ...

Conclusions. Direct hydrocarbon SOFC operation using dry CH 4 has been successfully conducted on a Ni-SDC anode-supported cell at 700 °C. The cell voltage degrades at a rate of 1.33 mV h −1, but without cell collapse when the operation is terminated at 100 h.

A methane-fuelled solid oxide fuel cell (SOFC) with molten tin anode (Sn (l)-SOFC) is designed, fabricated, demonstrated and characterized.This SOFC design incorporates molten tin contained in an alumina crucible as anode for the solution of oxygen atoms transported to an anode | Yttria stabilized Zirconia (YSZ) electrolyte interface and provides bubble | molten tin interfaces for the reaction ...

Natural gas is a cheap and abundant fuel for solid oxide fuel cell (SOFC), generally integrating the SOFC system with methane pre-treating system for improving the stability of SOFC. In this paper, the accurate effects of methane processing strategy on fuel composition, electrical efficiency and thermal efficiency of SOFC are investigated based ...

Internal reforming is an attractive option offering a significant cost reduction, higher efficiencies and faster load response of a solid oxide fuel cell (SOFC) power plant. However, complete internal reforming may lead to several problems which can be avoided with partial pre-reforming of natural gas.

In biogas-SOFC systems, methane should be reformed to provide H 2 and CO, since direct electrochemical oxidation of methane does not practically contribute to the power generation. 11, 44 External steam reforming technique is commonly used for biogas-SOFC systems in order to provide an appropriate fuel, which increases the cost and complexity ...
