Hydrogen production from bioethanol appears as a suitable route to effectively feed fuel cells on-board and on-demand. We report the use of a silicon micromonolith with 1 million 3.3 m channels loaded with a noble metal-based catalyst to produce H2 from EtOH (SR and ATR) intended to feed microfuel cells for portable electronic devices. We achieved to produce as much as 130 L(H2)/mL(EtOH,liq)/mL(reactor), which is 470-fold the production obtained with the same catalyst over 0.9 mm microchannels.
