Versatile Direct Methanol Fuel Cell Power Supply/Battery Charger Cecelia Cropley Giner Electrochemical Systems, LLC Newton, MA 2003 Tri-Service Power Expo Norfolk, VA July 15, 2003

Slide 2

Outline Introduction to DMFCs Military Applications GES DMFC Power Supply/Battery Charger Conclusions/Summary

Slide 4

Giner Electrochemical Systems, LLC GES Approach to DMFCs Focus on Portable DMFC in 150W to 5+ kW Range Bipolar stack, working at high power thickness Minimizes stack weight, volume and cost Minor proficiency punishment contrasted with low power thickness Use flawless methanol fuel, on-load up weakening 0.5M to 1M Operate at 60-70°C Air at close barometrical weight supplied by a blower

Slide 5

Schematic of a Direct Methanol Fuel Cell System

Slide 6

Military DMFC Applications Direct substitution of batteries as force hotspots for electronic gadgets – 20 W Portable battery charger for optional batteries 150 to 500 W Manpackable or carried on "Donkey" Replacement for little compact diesel generators 2 to 5 kW

Slide 7

COMPARISON of DMFC WITH H 2/AIR PEMFC Advantages of Methanol Fuel Methanol has much higher vitality thickness than H 2 put away in chambers or in hydrides results in lower framework weight and volume Methanol is much more secure and less demanding to transport and handle than pressurized H 2 barrels refilling with methanol is simple

Slide 8

Advantages of Direct Methanol Technology Longer layer lifetime because of working in watery environment Reactant humidification is not required Compared to H 2 Systems with Methanol Reformer Low working temperature of DMFC results in low warm mark DMFC framework has speedier start-up and stack taking after DMFC framework is less difficult and has lower weight and volume

Slide 9

Disadvantages of DMFC Operates at lower cell voltage and lower ebb and flow thickness DMFC fuel productivity is lower Approx. 17% at present With advancement, foresee increment to 25%

Slide 10

Fuel Cell Performance Comparison

Slide 11

Fuel Comparison 1500-Whr Operation (incorporates tank)

Slide 12

Status of DMFC Technology Large number of organizations chipping away at DMFC innovation for customer applications Commercialization of DMFCs for mobile phones and tablets expected inside 2-3 years Cost of DMFCs is descending, and getting to be aggressive with Li batteries

Slide 13

Status of DMFC Power Supplies/Battery Chargers at GES Recently created 3 rd era DMFC battery charger 150 W Technology is promptly scaleable down to 50 W and up to 5+ kW GES is wanting to frame another organization to popularize the innovation Accepting requests for pre-generation units

Slide 14

GES DMFC Portable Power Supply/Battery Charger 150 W AC/DC power yield 15 pounds 10-liter volume Methanol stockpiling for 2 hours operation Rapid start-up; phenomenal burden taking after

Slide 15

Product Status 150-W complete framework Demonstrated effectively Accepting pre-generation orders 800-W module Project in progress with Parker Hannifin and Vectrix for half and half bike 1.5-kW stack Demonstrated and conveyed to JPL in Aug 01

Slide 16

Projected Size of Commercial Units

Slide 17

Conclusions GES has built up a lightweight convenient DMFC battery charger Methanol fuel has numerous points of interest for versatile applications DMFCs are nearing commercialization
