The main problems that have hindered the market penetration of these systems ar e the cost of the polymer electrolyte membrane presently used in these devices, the membrane dehydration at temperatures higher than 100-120°C and the methanol cross-over. A direct methanol fuel cell based on a high tempera ture proton conducting membrane with suitable conductivi ty and stability up to 130°-150 °C, with proper therma l and water management would become a viable system for mobile applications. Thus, of particular interest a re composite membranes with the filler exhibiting stro ng affinity towards water molecules [1, 2]. In the pre sent work, composite membranes with Nafion as the ion conducting matrix and Chabazite, Clinoptilolite and Mordenite as zeolite fillers have been prepared. Th...

Though, the recharge time for battery pack and the autonomy range can constitute a limit. An appropriate use of fuel cell technology in electric vehicles can now represent an advantageous choice both from a technical and economic point of view. This paper reports the results of the development of a hybrid electric city bus, performed by the synergy between fuel cell and batteries. A pure electric city bus, equipped with eight Zebra batteries, was acquired and modified in a fuel cell and batteries hybrid vehicle. In the final version the bus was equipped with six batteries and a hydrogen plant with a proton exchange membrane fuel cell system. In particular an innovative powertrain management, where even the time required for the terminal stops is used to charge the batteries by the fuel cell, is described. Set-up tests on the fuel cell system acquired are presented. Further, tests were conducted also on the battery pack working on board in a real route to demonstrate the capability of the reduced battery pack to drive the vehicle.

After thermal activation, Ni was mainly present as highly dispersed La2NiO4 on the surface of perovskite surface. The thermal reduction at 800 °C caused the occurrence of metallic Ni on the surface. Surface area was determined by BET measurement. The catalyst was used as anode in IT-SOFCs fed with methanol. Studies under steam reforming, partial oxidation and autothermal reforming of methanol were carried out at 800°C. A comparison was made between the performance of SOFCs fed with syngas or methanol. The results with methanol are promising both in terms of energy density as well as suitable performance for portable power sources.

International Journal of Hydrogen Energy, 1994

The influence of the electrocatalyst characteristics upon activity and stability for the oxygen r... more The influence of the electrocatalyst characteristics upon activity and stability for the oxygen reduction reaction in phosphoric acid fuel cell (PAFC) systems is widely established. The initial catalytic performance progressively decreases, even on a short-term basis, under operational conditions, due to several factors such as Pt dissolution, sintering and carbon corrosion. The performance of catalysts depends upon the morphological characteristics of the electrodes. The proper tailoring of the Pt/C catalyst plays a fundamental role in obtaining high overall performance in such electrochemical devices. A high mass activity (mA mg−1) and low voltage decay are found, in the present investigation, for catalysts having Pt surface area above 80 m2g−1. Such results have been tentatively interpreted in terms of the acid-base properties of the surface, as determined by a potentiometric titration technique.

Research paper thumbnail of Investigation of IrO2 electrocatalysts prepared by a sulfite-couplex route for the O2 evolution reaction in solid polymer electrolyte water electrolyzers

International Journal of Hydrogen Energy, 2011

By using a sulfite complex-based preparation procedure, an amorphous iridium oxide precursor was obtained at 80 °C, which was, successively, calcined at different temperatures: 350 °C, 400 °C and 450 °C. A physico-chemical characterization was carried out by X Ray Diffraction (XRD), Transmission Electron Microscopy (TEM) and X-ray-photoelectron spectroscopy (XPS). The various IrO2 catalysts were sprayed onto a Nafion 115 membrane with a loading of 2.5 mg cm−2 to form the anode. A Pt/C catalyst (Pt loading 0.5 mg cm−2) was used as cathode. The best electrochemical performance was obtained for the cell based on the IrO2 calcined at 350 °C. The maximum current density at high potentials (1.8 V) was about 1.75 A cm−2. Accelerated time-tests at 2 A cm−2 demonstrated a suitable stability of the IrO2 calcined at 350 °C; however, the intrinsic stability appeared to increase with the calcination temperature. The sample calcined at 400 °C could represent a good compromise between performance and intrinsic stability.

It has identified seven key value chains in which to intervene, with the battery and vehicle value chain being one of them. Thus, actions and strategies for the sustainability of batteries need to be developed. Since Life Cycle Assessment (LCA) is a strategic tool for evaluating environmental sustainability, this paper investigates its application to two configurations of a sodium–nickel chloride cell (planar and tubular), focusing on the active material and the anode, with the purpose of identifying the configuration characterized by the lowest environmental impacts. The results, based on a “from cradle to gate” approach, showed that the tubular cell performs better for all environmental impact categories measured except for particulate matter, acidification, and resource depletion. With nickel being the main contributor to these impact categories, future sustainable strategies need to be orient...

At LENI Laboratory at EPFL, SOFC cells and stacks are designed, tested and analysed in collaboration with industry, from small area single cells to now kW-range stacks integrated in a system. The hardware R&D effort is strongly assisted by, and dependent on, modeling activities, for both design (e.g. new geometries) and understanding (e.g. degradation phenomena). This modeling has to occur on different levels, from the electrochemistry on micron-scale, via fluid dynamics on mm-scale, to thermodynamic+economic optimization of an entire system on m-scale. The modeling, finally, is accompanied by validation experiments. The presentation will give an overview of the SOFC research status at LENI with application examples.
