Abstract

Microcombustors provide many advantages over electrochemical cells as sources to power microsystems. A microfabricated thermal sensor (resistance thermometer/RTD type) has been employed to measure the amount of heat produced due to the combustion of H2/O2 nanobubbles created by electrolysis in such a microcombustor. It has been observed that combustion occurs above a threshold frequency of 15 kHz. The local surface heat produced initially increased linearly with frequency but at higher frequencies, it showed a non-linear tapering increase. An average surface heat value of 8×104 W/m2 was measured, which was in close agreement with the theoretical power of 1×105 W/m2 produced from the H2/O2 combustion obtained using the steady-state current value.
