Key Performance Criteria
The Membrane | Catalyst InterfaceEverything in the right place at the right time
• Catalysts are used to promote the forward reaction
• Catalyst must be in contact with:
1. Ionic conductor (membrane)
2. Electronic conductor (electrode)
3. Reactant (hydrogen or oxygen)
• Electrodes must be permeable to reactants & products
• Membrane must conduct ions not electrons
• Membrane must have a low hydrogen permeability
ITM POWER | Final Results Presentation, 30 July 2010ITM POWER | Hannover Messe, 2011
Key Performance Criteria
The Classic Polarisation CurveLow voltage, high current devices
• Voltage diminishes with current draw
• Zone 1: Catalyst & Gas Permeability
Zone 1 Zone 2 Zone 3
• Zone 2: Membrane Resistance
• Zone 3: Mass Transport Restriction
• Typical operating point 600 - 700mV
• Multiple cells used in a ‘stack’
