Abstract
We here report on the development of the fuel generation chip for micro fuel cell devices. In the chip, H and O are generated by the photocatalyic water splitting and the generated gases are separated by hydrophobic modified channels. To verify the basic concept that water splitting and the gas-liquid separation are driven solely by light energy, we prepare a chip in which electrodes (TiO photoanode and Pt cathode) and partial surface modification are integrated. The photocatalytic water splitting and the gas-liquid separation were verified, respectively. Copyright © (2011) by the Chemical and Biological Microsystems Society.
