Syngas (CO-H 2 ) production using high temperature micro-tubular solid oxide electrolysers

High-performance fuel cell designed for coking-resistance and efficient conversion of waste methane to electrical energy

“…When the inlet gas contains high percentages of inert diluent (set at 80%), the driving force for fuel diffusion decreased accordingly. It is noteworthy that although CO is also a gaseous fuel, H 2 had a slightly lower equilibrium potential difference (0.9839 V) than that of CO (0.9907 V) relative to oxygen reduction at 1027 K, 38 and a much greater self-diffusion coefficient (11.3 vs. 1.7 cm 2 s À1 at 1027 K). 39 Under the operating conditions used, hydrogen was expected to be oxidized preferentially, so CO was assumed to be 'sluggish or inert' during CFD modelling.…”

Thermodynamic analysis of high temperature steam and carbon dioxide systems in solid oxide cells

“…In accordance with the prediction, the ndings presented in ref. 32 show negligible methane formation during co-electrolysis of a H 2 O-CO 2 -rich mixture with H 2 and CO at temperatures around 800 C and 1.8 V, using helium as an inert gas halving the effective partial pressure of the active components, see point k 1 in Fig. 5.…”

Proton conductors and their applications: A tentative historical overview of the early researches

“…[85] Yet, their development is still in continuation. [81][82][83][84][85] At the same time, pressurized electrolyser and industrial prototypes of fuel cells in association with many stacks are in development. [66,67] [45] for solid acid sulphates in 1950 after…”

“…The attention is focused on the period before 2000, but some recent/review papers are also added to represent some links with the last developments. [81][82][83][84][85]…”
