Abstract
At present work, we report on the development of fuel generation chip driven by the solar light for portable micro fuel cell devices. In the chip, fuel (H and O ) are generated by the integrated photocatalyic water splitting system utilizing bottom up and top down technologies. Generated gases are separated by specially designed hydrophobic modified channels. We describe the device concept and fabrication technologies to integrate the photocatalytic system (which is based on TiO brush type nanorods structure) in the microchip. Also we demonstrate the working principle of the H /O generation microchip under the solar light and the maximum of photocurrent density ~35-20 μA/cm has been recorded during the gas generation and separation.
