Use of gasification syngas in SOFC: Impact of real tar on anode materials
TL;DR: In particular, tars have been identified as one of the major impurities in biomass and coal gasification fuel gas, causing degradation of the anodes due to carbon deposition as discussed by the authors.
Journal ArticleDOI
An experimental study of the interaction between tar and SOFCs with Ni/GDC anodes
TL;DR: In this article, the effect of carbon dioxide that is capable of suppressing carbon deposition was experimentally investigated, and an enhanced performance was observed under the conditions studied, indicating that tar performs as fuel for SOFCs.
Journal ArticleDOI
The effect of heavy tars (toluene and naphthalene) on the electrochemical performance of an anode-supported SOFC running on bio-syngas
TL;DR: In this paper, the effect of heavy tar compounds on the performance of a Ni-YSZ anode supported solid oxide fuel cell was investigated, and both toluene and naphthalene were chosen as model compounds and tested separately with a simulated bio-syngas.
Journal ArticleDOI
Limiting factors for planar solid oxide fuel cells under different trace compound concentrations
TL;DR: In this article, the performance of anode supported solid oxide fuel cells under the influence of different trace compounds was investigated and the results showed how the ohmic contribution is almost independent of the H2S concentration.
