Sabik Informationssysteme GmbH Direct Methanol Fuel Cell IALA-BAT Copenhagen 2008 By Morten Christensen

Direct Methanol FC  Converts methanol to electrical energy  30% efficiency  Uses undiluted methanol  Simple system, few components  NO GAS  High energy density 1 l ≈ 100 Ah for load 115 W DMFC Stack

DMFC System MeOH Supply MeOH Supply Water Tank CO 2 Out Filter Water Out Air In Condenser DC/DC Battery Humidifier Stack Heat Exchange Circulation Tank

DMFC in AtoN Weather independent Power on demand No self-discharge Easy to increase capacity  Re-fueling  Moving/rotating parts  Limited Stack Lifetime  New (unproven) Technology SABIK 100 W DMFC System

AtoN Applications Hybrid with Solar  FC to support in the winter time Back-Up  FC to supply if mains fails Stand-alone  Light powered by FC only Solar Charger

Technology Demonstrator  Lighthouse power supply  100 W DMFC Unit for battery charging  Buffer battery 120 Ah/ 12V  Flashing beacon 100 W  Outdoor installation Technology demonstrator made for the German Waterway Administration

Conclusion  Not yet on Hydrogen-FC level  Commercial available mainly for leisure activities, not yet for high reliability applications.  Stack Life-time increase  Key component cost decrease fast  100 W Unit for AtoN available 2009  250 W Unit for AtoN available 2010
