Abstract

Abstract:

As an attractive energy conversion system, solid oxide fuel cell (SOFC) has a broad development prospect due to its high energy conversion efficiency, environmental friendliness, and wide fuel selectivity. To date, Ni-based anode is the most commonly used anode material for SOFCs from the view of low cost, good stability, and high catalytic activation. However, the carbon deposition is demonstrated to be a main issue when using hydrocarbon as the fuel, leading to the reduction of the output performance and operational stability of SOFCs. Therefore, it is of important scientific significance that the carbon deposition mechanism and promotion strategy of SOFCs are studied. We review recent advances in the carbon deposition mechanism and improvement strategy of Ni-based anode SOFCs. The latest research progress and future development direction of several anode materials are also summarized and analyzed. This work provides a valuable reference for the further development of high-performance SOFC anode materials.
