Non-Reforming SOFC with High Efficiency

Performance analysis of a SOFC under direct internal reforming conditions

This paper presents the performance analysis of a planar solid-oxide fuel cell (SOFC) under direct internal reforming conditions. A detailed olid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency nd power density are observed for isothermal and adiabatic operational regimes. The influence of air numbe...

Reforming of JP-8 in Microplasmas for Compact SOFC Power

The attractive aspects of fuels cells for replacement of batteries in lightweight applications are offset by the need to efficiently produce a hydrogen feed stream on demand. Hydrogen is itself impractical for storage and hydrocarbon fuels provide the highest density form of hydrogen storage when taking into account both weight and volume. Currently, traditional catalytic processes are used for...

Biodiesel reforming with a NiAl2O4/Al2O3-YSZ catalyst for the production of renewable SOFC fuel

Biodiesel’s contribution as a renewable energy carrier is increasing continuously. Fuel cell market penetration, although slow, is now an irreversible reality. The combination of solid oxide fuel cells (SOFC) with biodiesel offers considerable advantages because it entails both high energy conversion efficiency and nearzero atmospheric carbon emissions. This work is aimed at proving the efficie...

A Strategy for Achieving High-performance with SOFC Ceramic Anodes

A proposal that high solid oxide fuel cell (SOFC) anode performance can be achieved by using a very thin, catalytically active functional layer, with a noncatalytic conduction layer, has been tested. An anode impedance of 0.26 Ω cm2 was obtained at 973 K in humidified H2 using a Ag-paste conduction layer and a 12 μm thick functional layer made from 1 wt % Pd and 40 wt % ceria in yttria-stabiliz...
