The study demonstrates that utilizing kelp biochar as fuel in DC-SOFC shows superior performance compared to traditional activated carbon and catalyst-loaded activated carbon fuels, offering a promising pathway for alternative biomass utilization in DC-SOFCs.
Direct carbon solid oxide fuel cell (DC-SOFC) is a larruping type of fuel cell due to its all-solid-state structure, which can generate electricity from converting the chemical energy contained in solid carbon fuels directly into electrical energy. As the most abundant carbon storage base on earth, besides commercial carbon, coal or the common biomass carbon fuels, the exploitation of marine biomass as an alternative fuel for DC-SOFC is a very intriguing topic. In order to make efficient utilization of biomass carbon obtained from the ocean, a high performing direct carbon solid oxide fuel cell fuelled by kelp biochar is demonstrated. As comparison, the performances of DC-SOFCs with activated carbon and catalyst-loaded activated carbon fuels are also investigated. Thereinto, the best performance of 285 mW cm(-2) at 850 degrees C is achieved in a DC-SOFC using kelp biochar fuel with Ag-Gd0.1Ce0.9O2-delta/YSZ/Ag-Gd0.1Ce0.9O2-delta configuration. This study will provide promising utilization of alternative biomass in DC-SOFCs and broaden their available carbon scope. (C) 2021 Elsevier B.V. All rights reserved.
