Nanostructured palladium–La0.75Sr0.25Cr0.5Mn0.5O3/Y2O3–ZrO2 composite anodes for direct methane and ethanol solid oxide fuel cells

Nickel‐Iron Alloy Nanoparticle‐Decorated K2NiF4‐Type Oxide as an Efficient and Sulfur‐Tolerant Anode for Solid Oxide Fuel Cells

“…Combining a perovskite with other conductors or active catalysts to form a composite anode is a useful method for enhancing the electrochemical activity of the anode . Generally, the main methods for the addition of second phases such as ionic conductors and active metals include physical mixing (PM) and infiltration . However, the contact of the two phases in the composite anodes prepared by the PM method was weak, which led to inferior operational stability.…”

“…[19][20][21][22] Generally, the main methods for the addition of second phases such as ionic conductors and active metals include physical mixing (PM) and infiltration. [19][20][21][22] However, the contact of the two phases in the composite anodes prepared by the PM method was weak, which led to inferior operational stability. The infiltration method has been demonstrated as one of the most useful and facile ways for adding an active metal and/or ionic-conducting phase to the anode, improving the performance by expanding the reaction to the entire anode volume, enlarging the number of the active sites and improving the contact of the two phases in the composite anode.…”

Effect of Pd-impregnation on performance, sulfur poisoning and tolerance of Ni/GDC anode of solid oxide fuel cells

“…Given the strong tendency of the growth and segregation of impregnated Pd nanoparticles [7,71], the effectiveness of site competition could decrease with the grain growth and segregation of impregnated Pd. This appears to be the reason for the gradual deterioration of the performance of Pd-impregnated Ni/GDC anodes in H 2 SeH 2 fuels (Fig.…”

Direct Ethanol Anode-Supported Solid Oxide Fuel Cell

“…In this context, preserving the Ni cermet as the anode and adding a catalytic layer to allow the gradual internal reforming (GIR) has been pointed out as promising strategy (13)(14)(15)(16). In the GIR process, the water released by the electrochemical oxidation of hydrogen at the anode is used for the steam reforming of the fuel in the catalytic layer deposited onto the anode (13,18,19).…”
