“…Unfortunately, this is accompanied by a reduction in conductivity. Attempts to improve conductivity have involved the use of new electrolytes, thinner membrane layers, new fabrication techniques and nano-material dopings [72]. As with PEMFC, the use of hydrogen as a base fuel is a significant logistic challenge and so the use of SOFC has focused on reforming of hydrocarbon fuels (e.g., natural gas).…”

More effective energy production requires a greater penetration of storage technologies. This paper takes a looks at and compares the landscape of energy storage devices. Solutions across four categories of storage, namely: mechanical, chemical, electromagnetic and thermal storage are compared on the basis of energy/power density, specific energy/power, efficiency, lifespan, cycle life, self-discharge rates, capital energy/power costs, scale, application, technical maturity as well as environmental impact. It's noted that virtually every storage technology is seeing improvements. This paper provides an overview of some of the problems with existing storage systems and identifies some key technologies that hold promise.

), to cover a wide range of ceramic chemical characteristics. The chemical and microstructural stability of these oxides with the mixed carbonates were studied by powder X-ray diffraction, scanning electron microscopy, infrared and laser Raman spectroscopic techniques after reacting them at 690C for 1 h in air. The electrical performance of selected composites was evaluated using impedance spectroscopy, in air.

“…Interest in these systems, specifically the development of anodes, continues to be an active area of research [39,40]. There have been several reviews of direct hydrocarbon SOFCs without reforming units [13,41,42]. Although no reforming unit was used, they indicate that internal reforming occurs [13].…”

n-Hexadecane Fuel for a Phosphoric Acid Direct Hydrocarbon Fuel Cell

et al. 2015

The objective of this work was to examine fuel cells as a possible alternative to the diesel fuel engines currently used in railway locomotives, thereby decreasing air emissions from the railway transportation sector. We have investigated the performance of a phosphoric acid fuel cell (PAFC) reactor, with n-hexadecane, C 16 H 34 (a model compound for diesel fuel, cetane number = 100). This is the first extensive study reported in the literature in which n-hexadecane is used directly as the fuel. Measurements were made to obtain both polarization curves and time-on-stream results. Because deactivation was observed hydrogen polarization curves were measured before and after n-hexadecane experiments, to determine the extent of deactivation of the membrane electrode assembly (MEA). By feeding water-only (no fuel) to the fuel cell anode the deactivated MEAs could be regenerated. One set of fuel cell operating conditions that produced a steady-state was identified. Identification of steady-state conditions is significant because it demonstrates that stable fuel cell operation is technically feasible when operating a PAFC with n-hexadecane fuel.
