Private and Confidential © 2011 A fundamentally lower cost, more reliable PEM Fuel Cell System FlowCath ® replaces up to 90% of the expensive platinum catalyst found in a PEM Fuel Cell with a safe, low cost, water-based catalyst solution. Which eliminates the need for membrane dehydration, has no peroxide attack, and no catalyst deactivation that leads to improved reliability and robustness At the same time it eliminates the need for humidification, air and fuel pressurization, and a separate cooling system. Provides cost savings of 40% and greater over conventional PEM Fuel Cell systems. Technology can be applied to PEM Fuel Cells from 1 to 200kW+ in size.
