Co-free La0.6Sr0.4Fe0.9Nb0.1O3-δ symmetric electrode for hydrogen and carbon monoxide solid oxide fuel cell

Effects of Sn doping on the manufacturing, performance and carbon deposition of Ni/ScSZ cells in solid oxide fuel cells

“…Although Ni is an excellent catalyst for both electrochemical oxidation reaction and reforming reaction in producing hydrogen and syngas (H2 and CO) [44][45][46][47][48], Ni also prone to carbon deposition. Hence, Ni-free anode with alternative metal [6,17,49] and perovskites material [50,51] On the other hand, Singh et al [42] and Lay et al [61] reported no significant performance difference and higher amounts of carbon observed on the Sn doped cells compared to the undoped cells with either low steam to carbon ratio. Troskialina et al [27] and Jiang et al [60] tested Sn-Ni/YSZ with dry biogas fuel instead of humidified hydrocarbon fuel.…”

Lignocellulosic biomass as sustainable feedstock and materials for power generation and energy storage

“…H 2 is an ideal fuel for SOFC with the highest fuel utilization efficiency [141]. CO can also be used as fuel, however, the electrochemical oxidation kinetics of CO fuel is lower than H 2 , since CO has a larger molecular weight and lower diffusion rate [142]. Methane is a promising fuel for SOFC as well.…”

“…Perovskite anodes have been reported to have good carbon and sulfur resistance [147]. Introducing perovskite-type oxides [142] and metal nanoparticle catalysts [130] into the Ni/YSZ anode can also significantly reduce the formation of carbon in the surface area of anode Ni and the adsorption of sulphur. In addition, a CeO 2 anode doped by a transition metal also has better sulfur resistance and carbon deposition resistance [135].…”

Cobalt‐Free Pr0.5Ba0.4Sr0.1FeO3–δ as a Highly Efficient Cathode for Commercial YSZ‐Supported Solid Oxide Fuel Cell

“…[19] Accordingly, a buffer layer is required to prevent the formation of insulating secondary phases between cobalt-based cathode materials and the YSZ electrolyte. [20,21] In this respect, it is of great importance to developing cobalt-free cathode materials with good electro-catalytic activity toward ORR.…”

“…Unfortunately, the utilization of these materials as SOFC cathode is hindered by their thermo‐mechanical mismatch with the YSZ electrolyte, high price of cobalt element, and chemical reactivity under cell operational condition [19] . Accordingly, a buffer layer is required to prevent the formation of insulating secondary phases between cobalt‐based cathode materials and the YSZ electrolyte [20,21] . In this respect, it is of great importance to developing cobalt‐free cathode materials with good electro‐catalytic activity toward ORR.…”
