1 HIGH POWER DENSITY FUEL CELLS HANNOVER MESSE, 2012 ITM POWER DESIGNS AND MANUFACTURES HYDROGEN ENERGY SYSTEMS FOR ENERGY STORAGE AND CLEAN FUEL PRODUCTION Dr Simon Bourne, Chief Technology Officer April, 2012

2 HIGH POWER DENSITY FUEL CELLS HANNOVER MESSE, 2012 Contents Company Introduction ITM s Unique Materials Early Results with Oxygen Polymer Fuel Cells Challenge Initial Results with Air Outlook ITM POWER DESIGNS AND MANUFACTURES HYDROGEN ENERGY SYSTEMS FOR ENERGY STORAGE AND CLEAN FUEL PRODUCTION Dr Simon Bourne, Chief Technology Officer April, 2012

3 HIGH POWER DENSITY FUEL CELLS HANNOVER MESSE, 2012 Background First stock market listed hydrogen fuel cell company Listed in 2004 secondary fundraising in employees Two locations in Sheffield 9m of cash resources First revenues achieved in Q ITM GmbH established 2011 ITM POWER DESIGNS AND MANUFACTURES HYDROGEN ENERGY SYSTEMS FOR ENERGY STORAGE AND CLEAN FUEL PRODUCTION Dr Simon Bourne, Chief Technology Officer April, 2012

4 POSITIONING HYDROGEN ENERGY STORAGE HYDROGEN TRANSPORT FUEL

5 THE CHALLENGE Electricity cannot be easily stored Renewable power cannot be scheduled Balancing supply and demand Required at small & large scale Energy storage required for long periods Represents major barrier to adoption of renewables POSITIONING ENERGY STORAGE CLEAN FUEL

6 THE SOLUTION Energy storage by DSM hydrogen production Modular, scalable and rapid response High conversion efficiency Ability to accommodate intermittent input Separates power from energy POSITIONING ENERGY STORAGE CLEAN FUEL

7 MATERIALS UNIQUE MEMBRANE MATERIALS THE KEY TO FUEL CELL PERFORMANCE

8 ITM S SUITE OF MEMBRANE MATERIALS A low cost, high efficiency membrane Hydrocarbon materials Cross-linked structure In-house formulation control Ease of production Acid/alkali chemistries possible Patented worldwide A HYDROCARBON MEMBRANE ENERGY STORAGE CLEAN FUEL

9 THE UNIQUE CHARACTERISTICS Membrane properties & interactions High & controllable water content t (>50% typ) High IEC (1.4 mmol/g typ dry) Maintains conductivity at low RH (28% higher than N212) Catalyst deposition during polymerisation for low loadings Incorporation of ITM ionomer in catalyst ink Conformability of surface N NH CH 3 O O N H 2 C S OH O CH 3 O H 2 C H 2 C Acrylonitrile Vinyl pyrrolidinone AMPSA Allyl methacrylate H 2 C CH 3 O O CH 2 A HYDROCARBON MEMBRANE ENERGY STORAGE CLEAN FUEL

10 THE UNIQUE CHARACTERISTICS Key fuel cell metrics Power density (W/cm 2 ) Operating voltage (V efficiency) Catalyst loading (mg/cm 2 ) Sensitivity to humidity (ms/cm vs %RH) Longevity A HYDROCARBON MEMBRANE ENERGY STORAGE CLEAN FUEL

11 EARLY RESULTS HYDROGEN/OXYGEN & BENCHMARKING

12 Hydrogen & Oxygen 30 psi RESULTS SNAPSHOT POWER DENSITY

13 EARLY BENCHMARKING Comparison with existing materials Identical polarisation tests ITM & Nafion 212 Same cells, conditions and GDL Pressed contact only Hydrogen/Oxygen yg ITM membrane ~120um thick RESULTS SNAPSHOT POWER DENSITY

14 THE PFCC INITIAL RESULTS WITH HYDROGEN/AIR AUTOMOTIVE APPLICATIONS

15 THE FUEL CELL MEA Power Density Increasing power density is key! Funded project with the Carbon Trust Focus on automotive requirements Characterisation of membrane and MEA Achievement of 2.1W/cm 2 at 4.2A/cm 2 OEM engagement RESULTS SNAPSHOT HYDROGEN AIR

16 THE FUEL CELL MEA Operating Voltage Cell Efficiency 1W/cm 2 at 55% efficiency i Matches NOW analysis of OEM needs Highlights need to balance efficiency Independent cost analysis RESULTS SNAPSHOT OEM TARGETS & EFFICIENCY

17 THE FUEL CELL MEA Sensitivity to Catalyst Loading Ak key element prior to longevity testingti Pt Black not effective at low loadings Supported Pt favourable but complex Post coating have shown advantage 85% reduction in Pt at 90% power density RESULTS SNAPSHOT CATALYST LOADING

18 THE FUEL CELL MEA Sensitivity Relative Humidity Water retained within structure t due to additional hydrophilic hili groups In-situ MEA conductivity at 60 o C (0.5A/cm 2 ) Benchmarked against N212 ITM membranes exhibit higher conductivity RESULTS SNAPSHOT CONDUCTIVITY VS RH

19 THE FUEL CELL MEA Longevity performance Difficulties remain in test t environment No irreversible degradation observed over 24 hr Limited durability testing undertaken Modest test capacity RESULTS SNAPSHOT DURABILITY
