Abstract

Electricity generation from biomass offers a promising approach to reduce carbon emissions. In conventional partial oxidation (POX) of biomass carbon, the Gibbs free energy loss reaches 202.332 kJ/molC, accounting for 51.11% of the total, which severely limits the achievable electrical output. To address this, we propose a liquid metal electrochemical partial oxidation (EPOX) method based on a liquid antimony anode solid oxide fuel cell (LAA-SOFC), which decouples the direct oxidation into two steps via an Sb/Sb2O3 redox pair, allowing efficient extraction of electrical energy and reducing the Gibbs free energy loss to 14.07% under ideal conditions. A four-cell LAA-SOFC stack demonstrated 10.1 W peak power with 120-h stability. System-level thermodynamic simulations reveal that the LAA-EPOX reduces fuel cell exergy loss proportion in hybrid power system from 40.20% to 29.80%, boosting system efficiency from 64.86% to 70.99%. Techno-economic analysis reveals a 15.51% capital costs reduction and reduced electricity cost from 0.0928 to 0.0831 $/kWh for biochar, offering an efficient pathway for complex fuel power generation.
