“…355 Hence, it is similar to phosphoric acid fuel cells (PAFCs), which operate in the range of 180 to 200°C. 356 PAFCs have been modeled and experimentally explored, and a review of them is outside the scope of this article. Many of the features of PBI cells are similar to those PAFCs including problems of acid leaching and durability concerns of the electrodes and gains of high conductivity and minimal water management.…”

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

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.

“…Silver membrane cathodes (1 cm 2 ) were floated on the surface of a fresh KOH solution with the other side exposed to an oxygen (High purity grade N6.0) or air atmosphere through forced convection [30]. Cathodes were polarised after 15 min in contact with the electrolyte under oxygen in a first scan (0.01 V/s) from OCV (1.1 V) to 0.1 V for conditioning.…”

Abstract:Porous silver membranes were investigated as potential substrates for alkaline fuel cell cathodes by the means of polarisation curves and electrochemical impedance spectroscopy measurements. The silver membranes provide both electrocatalytic function, mechanical support and a means of current collection. Improved performance, compare to a previous design, was obtained by increasing gas accessibility (using Teflon AF instead of PTFE suspension) and by adding a catalyst improvement compare to the previous design.
