Around 50,000units are now operated in Japanese household. Large Scale Monitoring Slide 4 Copyright 2013 Toshiba Fuel Cell Power Systems Corporation. All rights reserved. In advance of commercialization, over 3,300unit of residential PEFC were installed and verified in FY2005 through 2008 under governmental program. In the program, system showed enough performance and reliability as future commercial product. Large Scale Monitoring Program by Japanese Government 4 Thermal Load of each House [MJ/month] The Amount of CO2 Reduction [kg/month] Five system manufacturers joined to the program, and delivered 3,307units. Toshiba delivered 748 units among them. Residential PEFC showed the performance to reduce 100kg/month of CO2 as the average. Slide 5 Copyright 2013 Toshiba Fuel Cell Power Systems Corporation.

Start commercialization The sales volume has been increased year by year. Accumulated volume is expected to be more than 40,000unit in FY2012 * the volume of 2012 is roughly estimated based on subsidy condition as of end of August Fiscal year Annual volume] Trend of sales volume Another 53k for FY2013 by METI 2013 5 Slide 6 Copyright 2013 Toshiba Fuel Cell Power Systems Corporation.
