1 //0 Laila Grahl-Madsen September, 0 Demonstration of H fuelled µchps based on LT PEMFC in Vestenskov IRD A/S is an independent high technology company devoted to Research & Development and production of fuel cells and fuel cell systems. The product range comprises: - PEM Fuel Cell components (MEAs & bipolar plates) - Direct Methanol Fuel Cell modules (DMFC) - H -fuelled µchp - PEM-electrolyser [H (g) -generator] IRD was founded in 99 and is now employing 0 highly competent colleagues within the Fuel Cell Industry

2 //0 The overall demonstration project have developed and tested three () technologies 006-0: Demonstration of Micro CHP Based on Danish Fuel Cells Phase : Energinet.dk (J.N o ) Phase : The Danish Energy Authority (EFP-Akt.67 J.
