“…The SPE are polymers with insulating properties mixed with substances that provide ions such as salts and acids. These ions, which are coordinate with polymer atoms, provide the ionic conduction required for applications in rechargeable batteries, electrochromic windows, fuel cells and humidity sensors, and in wide variety of portable devices [1]. The diversity of shapes and sizes, and the operating conditions of these devices, have generated great interest in the search of SPE with properties such as higher ionic conductivity (σ > 1x10 -5 S cm -1 ), better mechanical flexibility and wider thermal and electrochemical windows.…”

ABSTRACT:Composites formed by combinations of polyethylene oxide (PEO) and sodium trifluoroacetate (CF 3 COONa) with different aluminum oxide (Al 2 O 3 ) concentrations were synthetized. Infrared (IR), Raman spectroscopy, X ray diffraction (XRD) and atomic force microscopy (AFM) analyses, were performed to characterize the composites. Changes on the XRD intensity peaks, and variations in intensity and position of some peaks in Raman and IR spectroscopy were observed for different concentrations of added Al 2 O 3 . The decrease in the XRD peaks of the PEO when it is combined with the salt, revealed that crystallinity in polymer was reduced, being lower when the alumina is added. The increase in roughness root medium square (R RMS ) observed by AFM when Al 2 O 3 was added, agree with reduction in crystallinity observed with XRD studies. Changes in the structure of PEO showed in the absorption lines IR and Raman, due to addition of CF 3 COONa salt and Al 2 O 3 filler, have been attributed to the interactions between the electrolyte and the filler. RESUMEN:Se sintetizaron compósitos formados entre polióxido de etileno (PEO) y trifluoroacetato de sodio (PEO 10 CF 3 COONa) con diferentes concentraciones de óxido de aluminio (Al 2 O 3 ). Los compósitos fueron caracterizados por espectroscopía infrarroja (IR), espectroscopía Raman, difracción de rayos X (XRD) y microscopía de fuerza atómica (AFM). Las combinaciones del electrolito sólido PEO 10 CF 3 COONa con diferentes concentraciones de Al 2 O 3 , mostraron cambios en la intensidad de los picos de XRD, así como cambios en la intensidad y posición de algunos picos de IR y Raman. El decrecimiento de los picos del PEO en XRD, cuando este fue combinado con la sal, reveló que la cristalinidad del polímero se redujo, siendo más baja cuando se le adicionó alúmina. Se observó un incremento en la raíz cuadrática media de la rugosidad (R RMS ) obtenida por microscopia de fuerza atómica cuando se adicionó Al 2 O 3. Este incremento está en concordancia con la reducción de la cristalinidad observada con estudios de XRD. Los cambios en la estructura del PEO mostrados en las líneas de absorción de IR y Raman, debidos a la adición de CF 3 COONa y Al 2 O 3 , fueron atribuidos a interacciones entre el electrolito y el relleno Al 2 O 3 .

Experimental Evaluation of Supercapacitor-Fuel Cell Hybrid Power Source for HY-IEL Scooter

et al. 2013

This paper presents the results of development of a hybrid fuel cell supercapacitor power system for vehicular applications that was developed and investigated at the Energy Sources Research Section of the Wroclaw Division of Electrotechnical Institute (IEL/OW). The hybrid power source consists of a polymer exchange membrane fuel cell (PEMFC) stack and an energy-type supercapacitor that supports the system in time of peak power demands. The developed system was installed in the HY-IEL electric scooter. The vehicle was equipped with auxiliary components (e.g., air compressor, hydrogen tank, and electromagnetic valves) needed for proper operation of the fuel cell stack, as well as electronic control circuits and a data storage unit that enabled on-line recording of system and vehicle operation parameters. Attention is focused on the system energy flow monitoring. The experimental part includes field test results of a vehicle powered with the fuel cell-supercapacitor system. Values of currents and voltages recorded for the system, as well as the vehicle's velocity and hydrogen consumption rate, are presented versus time of the experiment. Operation of the hybrid power system is discussed and analysed based on the results of measurements obtained.

“…Many reports from different universities and commercial R & D institutes in the realm of fuel cells have been published to propose solutions to tackle the challenges such as those named above. The United States Department of Energy (DOE) are underway to lead the studies through the following targets: to replace or decrease platinum (Pt) dependency through the making alloys or finding suitable Pt-free electrocatalyst, to search for finding efficient methods for electrocatalyst dispersion, and to develop mass transport and increase performance through the use of proper supports [8][9][10][11][12].…”
