This paper presents a power supply module targeted for low-power applications in the sub-mW range incorporating a passive µDMFC fuel cell (µFC) acting as energy source and a customized boost converter for the energy conversion. The low power budget of such energy sources mandates the adoption of efficient circuit solutions, hence the design of the boost converter is challenging. To maximize the lifetime of the micro fuel cell, the module has been designed to keep constant the µFC operating point and it has been optimized to work with µFC providing a voltage in the range 280mV-320mV, reaching a maximum efficiency higher than 65% with an output power of 350 μW.

Abstract
This paper presents a power supply module targeted for low-power applications in the sub-mW range incorporating a passive µDMFC fuel cell (µFC) acting as energy source and a customized boost converter for the energy conversion. The low power budget of such energy sources mandates the adoption of efficient circuit solutions, hence the design of the boost converter is challenging. To maximize the lifetime of the micro fuel cell, the module has been designed to keep constant the µFC operating point and it has been optimized to work with µFC providing a voltage in the range 280mV-320mV, reaching a maximum efficiency higher than 65% with an output power of 350 μW.
