Focuses on the most important micro fuel cell applications, including Biomedical and Transport Engineering

Micro fuel cells may be the most promising technology for fulfilling the world's pressing need to store large amounts of power within small, light-weight units. The variety of potential applications for these fuel cells is astounding. Biomedical researchers believe that health-care devices powered by micro fuel cells could revolutionize everything from open-heart surgery to diabetes control. Major tech companies envision micro fuel cells as ideal for use in portable electronics because, unlike traditional batteries, they do not require recharging from an external source.

Micro Fuel Cells: Principles and Applications provides scientists, engineers and product designers with a unique reference to these increasingly vital power sources. Within this targeted text, a panel of distinguished scientists from around the globe elucidates she fabrication of micro fuel cell components and the assembly of systems based on them, while focusing on key practical applications. Each chapter explores innovative recent developments in great detail and outlines the challenges that must be overcome in order to take this exciting technology to the next level.
