11 History of Toyota FCHV 2002 model Toyota FCHV World s 1st available vehicle in the market Received Model certificate Improved performance Total 18 vehicles are leased in Japan & US model Total 20 vehicles are leased in Japan & US. Toyota FCHV-adv World s top cruising range & cold start Total 14 vehicles are leased in Japan. Total 104 vehicles are now under introduction in US until 2011 for ZEV requirements. 5 vehicles are now in Germany for CEP program model 11

12 Challenge for FCEV Development FC stack Issues expected to be resolved ①Practical cruising range ②Refueling time ③Fuel cell start-up below freezing Motor High pressure hydrogen tank 2015 Issues need to be resolved ①Cost reduction FCV-R 70MPa high pressure hydrogen tank cruising range app.700km Japan JC08 Mode ②Reduction in size and weight ③Improving durability of FC stack ④Hydrogen supply infrastructure 12

13 Toyota FCHV-adv Long-distance Travel The cruising range has been significantly improved by increasing hydrogen tank pressure (35 MPa => 70 MPa) and system efficiency. (about 300 km => 500 km with practical driving cycle) Japan Tokyo Osaka Cruising range LA#4 790 km km 560km (350mile) Toyota in-house test With single refueling, FCHV-adv successfully traveled between Osaka and Tokyo (560km) under real-use condition (A/C on, etc.) 13

16 FC system cost FCEV System Cost Reduction FCHV-adv Low-volume production 1/20 or less Mass production Initial phase of market penetration Limited release phase Overcoming technical challenges Further cost reduction Growth phase of market penetration Reducing costs Design, material and production technologies Economies of scale We are focusing on achieving 1/20 cost reduction of FC system compared with the current FCHV-adv towards commercialization 16

17 Cost Reduction : Elimination of components Humidifying Inlet Air Air channel MEA H2 channel Air channel MEA H2 channel Out In Out In In Out In Out Moisture exchange Humidifier Eliminate Using humidifier system TOYOTA FCHV-adv ( 07MY) Not using humidifier system (future) We are trying to eliminate the external humidifier by re-circulating generated water in the FC stack itself 17

18 Cost Reduction : Re-circulation of generated water 2. Decrease carry out of generated water 1. air & hydrogen Counter flow Generated water H2 channel Air channel Dry air MEA 3. Thinner electrolyte membrane 4. Increase hydrogen recirculation 18

19 Cost Reduction : Reduction of CFRP usage & material cost High-pressure Hydrogen Tank CFRP ØD (for holding H2 gas pressure) Liner (for H2 sealing) L Cross-section of tank body Tank dimension (1) Reduce CFRP - Optimize layer structure (hoop winding / helical winding) - Optimize L/D - Optimize boss size (2) Reduce cost of CFRP - Aviation grade => General-purpose grade Develop low-cost CFRP for high-pressure tank 19

20 Reduction in size and weight New FC stack Power density has been more than doubled Achieved the world s highest level of 3.0 kw/l Reduced FC system size World s highest Allowing under-seat layout to be realized High-pressure hydrogen tank Decrease in number of tanks per vehicle from four to two Reduced costs Re-examination of materials used and manufacturing process 20
