Abstract

This study presents a detailed modelling and simulation of a Solid Oxide Fuel Cell (SOFC) system powered by hydrogen (H₂) blended with natural gas (NG). The model, validated with experimental data from pure NG operation, predicts system performance with an average error of 1.46 %. Simulations were conducted for two cases of hydrogen blending: before and after the reformer. A 5 % by volume H₂ blend before the reformer increases power generation by 0.9 – 1 % and thermal output by 0.15 %, while post-reformer blending results in a 1.5 – 3 % increase in power generation and a 1.4 % rise in thermal output along with reduced CO2 emission.
