nomura code cfcl report, page-4

excellent report...thank you!...can someone please re-read and comment on the "life span" bit of our fuel stacks? (i am not sure if I am reading it right)...they saying we have atm 3 year life span - after which efficiency drops - and we are working on 5 year life span (it may be delivered in automative production) and final aim is to get 15 years life span? is that right?...i am NOT technical minded at all and get muddled more then some when reading stuff of this sort...cheers!
