Effects of dispersed copper nanoparticles on Ni-ceria based dry methanol fuelled low temperature solid oxide fuel cells

Abstract

Copper impregnation was selected to decrease the carbon deposition and enhance the performance at low temperature of dry methanol fuelled low temperature solid oxide fuel cells.

A comprehensive review of solid oxide fuel cells operating on various promising alternative fuels

“…Different from methane that carbon formation is largely due to methane cracking reaction, deposited carbon in methanol-fuelled SOFCs is primarily generated from the decomposed carbon monoxide via Boudouard reaction (Eq. ( 9)) [207]. As demonstrated previously, forward Boudouard reaction is favourable thermodynamically at lower temperature, which indicates that carbon deposition would take place at relatively lower temperature (below 700 ℃ [92]).…”

Improved electrochemical performance and durability of butane‐operating low‐temperature solid oxide fuel cell through palladium infiltration

“…Effective efforts have been tried to solve the coking deposition over hydrocarbon steam reforming, and considerable progress has been obtained in recently. [20][21][22][23] The first method to suppress carbon deposition is by controlling the steam-to-carbon ratio (SCR). The SCR is the ratio of reactant water molecules to the number of carbon atoms in a hydrocarbon.…”

“…C 4 H 10 , with a higher carbon ratio, is thermodynamically more prone to coke formation in comparison with conventional methane fuel. Effective efforts have been tried to solve the coking deposition over hydrocarbon steam reforming, and considerable progress has been obtained in recently 20‐23 . The first method to suppress carbon deposition is by controlling the steam‐to‐carbon ratio (SCR).…”
