Portable Power Applications

Fuel cells provide a clean and efficient alternative fuel technology for transportation, residential and portable power applications. From political, social, economic, energy, environmental and technological considerations, the emerging fuel cell technology is undoubtedly well worthy of long-term investment in Taiwan. In view of the success and manufacture capability of electronics and IT industries, Taiwan may play an active role in fuel cell manufacturing and is thus conducive for international strategic alliance, both in R&D and manufacturing activities. This article provides an overview of Taiwan’s technological activities and accomplishments in fuel cells, and makes recommendations for the country’s future development and commercialization of fuel cell applications.

AbstractFuel cells have gained renewed interest for applications in portable power since the energy is stored in a separate reservoir of fuel rather than as an integral part of the power source, as is the case with batteries. While miniaturized fuel cells have been demonstrated for the low power regime (1-20 Watts), numerous issues still must be resolved prior to deployment for applications as a replacement for batteries. As traditional fuel cell designs are scaled down in both power output and physical footprint, several issues impact the operation, efficiency, and overall performance of the fuel cell system. These issues include fuel storage, fuel delivery, system startup, peak power requirements, cell stacking, and thermal management. The combination of thin-film deposition and micro-machining materials offers potential advantages with respect to stack size and weight, flow field and manifold structures, fuel storage, and thermal management. The micro-fabrication technologies that enable material and fuel flexibility through a modular fuel cell platform will be described along with experimental results from both solid oxide and proton exchange membrane, thin-film fuel cells.

Portable Power Applications

Fuels are being considered an as environmental friendly technology and are making headlines across the globe as clean and reliable alternate energy source for transportation, stationary and portable power applications. The rapid developments taking place in all the leading research laboratories in the world are making fuel cell closer to the realization. The progress of PEM fuel cell is closely related to the development of solid polymer electrolyte membranes as it defines the properties needed for other components of the fuel cell. So far perfluorosulfonated membranes such as Nafion have been found useful in these fuel cells and are the only material of choice available commercially. But these membranes are very expensive and have other drawbacks, which acts as an impediment for the commercialization of this technology. As a result alternative cheaper membrane materials have been developed. For the development of new or novel membranes mainly three strategies have been used: (1) modifying the currently used ionomer membranes (2) synthesizing new polymeric membranes and (3) develop new polymer composites by blending the two polymers or composting with an inorganic material. The composite membrane approach (3) has been widely used to tackle the problem of methanol crossover and temperature stability.

Portable Power

The high energy density available from polymer electrolyte membrane (PEM) fuel cell systems makes them attractive sources of portable power. A key consideration for minimum weight portable power systems is that they must operate simultaneously at water balance (no external water supply) and thermal balance (controlled temperature). Water and thermal management are intimately linked since evaporation is a potent source of cooling. The cell’s electrochemical performance and the ambient environment determine the rates of water production and transport as well as heat generation and removal. This paper presents the basic design relationships that govern water and thermal balance in PEM fuel cell stacks and systems. Hydrogen/air and direct methanol fuel cells are both addressed and compared. Operating conditions for simultaneous water and thermal balance can be specified based on the cell’s electrochemical performance and the operating environment. These conditions can be used to specify the overall size and complexity of the cooling equipment needed in terms of the “UA” product of the heat exchangers. The water balance properties can have strong effects on the size of the thermal management equipment required.
