Microscale (<5 W) reformers for hydrogen production have been investigated for over a decade. These devices are intended to provide hydrogen for small fuel cells. Due to the reformer's small size, numerical simulations are critical to understand heat and mass transfer phenomena occurring in the systems and help guide the further improvements. This paper reviews the development of the numerical...
A micro-scale power supply is being developed to provide an alternative to current secondary batteries for use in microelectronics devices, such as microsensors. The work discussed in this paper expands on this earlier reported sub-watt power generation system. Two designs were evaluated: a processor optimized to improve the thermal efficiency of the methanol reforming reactor from 9 to above 20%,...
