Fuel Cell Powered Hearing Aids
Jan H. Hales, PhD, Centre for Microtechnology and Surface Analysis, Danish Technological Institute, Danmark
Hearing aid users are faced with the dexterity challenge of frequently replacing the small button cell batteries. This challenge becomes more pronounced as the energy demand of new hearing aids increases with functionality. The presented research addresses the replacement of zinc-air batteries with methanol based micro fuel cells. The presentation will focus on the development towards pilot production from the perspective of the involved research on large scale synthesis of catalytic nanoparticles and advanced fuel cell encapsulation.

Lightweight Hydrogen Cartridges for PEMFC
Stephen Voller, CEO, Cella Energy, United Kingdom
Cella Energy’s portable power division is based at the NASA Kennedy Space Centre in Florida. The company is developing new lightweight hydrogen cartridges that can be used with PEM fuel cells as battery charges or range extenders for smartphone’s, cloud computing devices, laptops and for the military. Cella’s patented technology changes the properties of complex hydrides so the hydrogen is released quickly and cleanly. Once produced the Cella materials look like Kleenex or tissue paper.

Development of a Low Cost, Highly Flexible Fuel Cell – Battery Hybrid Power Architecture
Shane Slater, PhD, CEO, LightGreen Power, United Kingdom
The capital cost and durability of fuel cells remain barriers to deployment. Many applications have an intermittent load profile, such as off-grid power, robotics, and electric flight. The characteristic high peak/average power can result in destructive on-off fuel cell cycling and early failure. A novel hybridisation architecture has been developed which permits smaller, cost effective fuel cells to be used in high power applications while improving durability. A key innovation is DC-DC conversion with variable voltage and current. This permits complete control, allowing modulation of the fuel cell output to improve duty cycle requirements and significantly improve lifetimes. Key advantages are lower cost, improved fuel cell durability, inclusion of diverse fuel cell / power generators, and simple, software based system configuration. The hybrid architecture has been deployed commercially in the LightGreen Power Micro and Hyball systems with fuel cells from 50-500W producing up to 3kW.

A Novel Proton Exchange Membrane Fuel Cell-Battery Partial Hybrid System Design for Unmanned Aerial Vehicle (UAV) Application
Maheboob (Mebs) Virji, Hawaii Natural Energy Institute (HNEI), University of Hawaii
A novel partial FCB hybrid system has been designed to have flexible modes of operation which would allow the fuel cell and the battery to share the peak power for extended periods, operate the fuel cell stack at much lower and better controlled dynamics and minimize the system losses. A prototype hardware controller has been designed and built to working in conjunction with the control algorithm of the partial hybrid system to enable the use of a smaller charging DC/DC converter and ”Zero-Volt” diode control switches to reduce the overall system losses.

Portable LPG-Fueled Microtubular SOFC
Sascha Kuehn, PhD, Managing Director, eZelleron GmbH, Germany
The demand for mobile power increases steadily. Mobile devices always seem to be out of power exactly when you need them. Batteries can fulfill the users “thirst” for power only in a short term range. Batteries need a long-term non-mobile recharging time. Thus, for the long-term mobile power supply without recharging interruptions or for mobile recharging of devices gasbatteries are the best choice. eZellerons gasbattery is a hybrid system of battery and fuel cell. For the user it feels like a standard battery with up to 30 times more energy per weight than a battery. The fuel cell can be easily fueled by everywhere available gases like propane, butane, campinggas or LPG. The fuel cell is a Solid Oxide Fuel Cell (SOFC), bringing the advantage of fuel flexibility and being free from noble metals. However, SOFCs have known issues, like slow start-up and bad cyclability. In this presentation it is shown, how to overcome these issues by engineering the microstructure. The mass-manufactured eZelleron microtubular SOFC is operational within seconds. Hence this is a potential technology for mobile/portable power supply of devices.

Mixed Ionic-Electronic Conducting Oxide with K2NiF4 Type Structure, Potential Cathode Material With for Intermediate Solid Oxide Fuel Cells
Mirela Dragan, PhD, Researcher, University of Connecticut
Mixed ionic-electronic conductors (MIECs) have received considerable interest over the last few years because of their applicability as oxygen-transporting membranes because they can be used in a wide range of applications such as cathode materials in solid-oxide fuel cells, the partial oxidation of methane to syngas, the production of high purity oxygen, in petrochemical processes such as the oxidative coupling of methane to ethylene or ethane. During of oxygen transport two basic processes occur in a single-phase ceramic material at steady state are discussed. In the bulk, coupled diffusion of oxygen ions and electrons takes place, while exchange reaction of oxygen from the lattice with molecular oxygen in the gas phase occurs at both interfaces of the membrane. Ceramic oxides materials with perovskite related structures, like the K2NiF4 structure have been reported to exhibit substantial oxygen permeation flux, which makes these attractive candidates for high-temperature oxygen separation. In contrast to perovskite type membranes, the oxygen flux in these materials is believed to be supported by oxygen interstitial ions. In this work mixed ionic-electronic conducting oxide with K2NiF4 type structure is evaluated with respect to the transport properties, stability in different atmospheres and the aging.

Integrated Fuel Cell / Battery Mobile Energy Systems
Salvatore J. Pace, PhD, Independent Consultant in Fuel Cell/Battery Technology
Arguably, a most promising technology for mobile energy systems is the integrated fuel cell/ battery system. However, the integration of source energy functions does not go far enough in achieving the efficiency necessary to provide a significant alternative for future transport systems (automobiles). Taking a cue from nature, energy source and function are closely coupled and confined to a single cell (where selective energy transfer and actuation or other function occurs). By adapting the tools of micro-fabrication and nanotechnology we can configure integrated system platforms that couple energy source and actuation as self-contained continuously refueled systems that mimic nature. Fuel cells are well suited for integrated electric motor design. Such systems may be fueled by Nat Gas/Air or other renewable fuels. Furthermore, the development of such motor/fuel cell platforms would provide the discovery mechanism for catalysis, the key to energy efficiency for such systems.
