“…be used for methanol fabrication [111]. Energy harvesting applications such as power generation from exhaust gases of heat engines in cars [222] or motorcycles [142,143] are also envisaged, as the low efficiency of SC-SOFCs can be compensated by the generation of electrical power from waste gases. Several examples of possible applications are detailed in the following sections.…”

“…The high temperature of the exhaust gases provides sufficient heat for fuel cell operation, while different hydrocarbon fuels and oxygen are available in the exhaust gas stream. The cell can be simply put inside the exhaust pipe, as demonstrated by the Hibino group [142,143]. A twelve-cell SC-SOFC stack delivered OCVs of 5-8 V and a power output of 1 W in the exhaust gas of a motorcycle.…”

Abstract:In single-chamber solid oxide fuel cells (SC-SOFCs), both anode and cathode are situated in a common gas chamber and are exposed to a mixture of fuel and oxidant. The working principle is based on the difference in catalytic activity of the electrodes for the respective anodic and cathodic reactions. The resulting difference in oxygen partial pressure between the electrodes leads to the generation of an open circuit voltage. Progress in SC-SOFC technology has enabled the generation of power outputs comparable to those of conventional SOFCs. This paper provides a detailed review of the development of SC-SOFC technology.

“…At the same time, not only electrolyte-supported SC-SOFC modules [7][8][9] but also stacks consisting of several cells have been fabricated and operated successfully in single-chamber conditions [10][11][12][13][14][15][16]. Some stack designs for SC-SOFCs have been presented, and good results have been obtained with them.…”

A Single‐Chamber SOFC Stack: Energy Recovery from Engine Exhaust

et al. 2008

The feasibility of applying single‐chamber solid oxide fuel cells (SC‐SOFCs) to power generators for exhaust energy recovery was investigated using both model and actual exhaust gases. In the experiments with model exhaust gases, a single cell, Ni‐Ce0.8Sm0.2O1.9/YSZ/La0.8Sr0.2MnO3, was operated in a mixture of gases containing ppm levels of CH4, C2H6, C3H8, C4H10 and O2. The cell performance was considerably affected by the molar ratio of total hydrocarbons to O2, the operating temperature and the gas flow rate. The optimal operating conditions of the SC‐SOFC were found to be similar to those found in actual exhaust from gasoline engines. Thermal and mechanical loading performance tests demonstrated high tolerance towards thermal cycling and breakage of the electrolyte. Performance tests with and without a gas separator suggested that there is no requirement for a gas separator in an actual exhaust. In the experiments with actual exhaust gases, a 12‐cell stack was installed to a 250‐cm3 engine. The open circuit voltages (OCVs) were between 5 and 8 V and independent of the number of revolutions, but were lower than the values expected from the model exhaust results. This was considered to be due to the deviation of the actual exhaust gases from the model gases. Nevertheless, the stack performance was reproducible and stable in the range from 1,500 to 5,500 rpm. The resultant peak power reached above 1 W at 4,500 rpm.
