A review on anode on-cell catalyst reforming layer for direct methane solid oxide fuel cells

The commercialization of solid oxide fuel cells (SOFCs) can be significantly promoted with the direct utilization methane, which is primary component in natural gas and second most abundant anthropogenic greenhouse gas. However, carbon deposition on commonly used Ni-based anode bottle-necking issue inhibiting long-term stability methane SOFCs. To avoid such a problem, typically reformed (internally or externally) Considering cost, system simplification, coking resistance, material selection, on-cell catalytic reforming layer (OCRL) one promising designs for Reforming materials are consisted active component, substrate promoter, all have significant impact activity, sintering resistance catalysts. This review summarizes influence various components, some common OCRL their applications SOFCs, mechanism, as well remaining challenges. effective plays pivotal role promoting development SOFCs
