This paper briefly reviews a variety of microdevices for miniaturized fuel-cell applications. Research and development in this field have been activated since late 1990s, when portable information devices, for example, laptop computers and cellular phones, were getting popular, but battery life was quite limited. To date, different types of micro-fuel cell, micro-fuel reformers, fuel handling microfluidic devices, and so on were developed, and some of them were installed and used in prototyped miniaturized fuel-cell systems. In this paper, selected examples are introduced, and problems/challenges as well as achievements are summarized.
