[PLUG-TALK] Vertical doped carbon nanotubes...

[Michael Robinson]

Are nitrogen doped carbon nanotubes the substitue for platinum
that will make fuel cells cheap enough and durable enough 
for them to be commercialized already?  I've been trying to 
find out when prototype fuel cell vehicles which don't use 
platinum electrodes in the fuel cell are going to hit the 
road, but I'm not having much luck.  Why do so many sites
say that fuel cell cars won't hit the commercial market for
another 10-15 years?  It seems that all the necessary 
technology for fuel vehicles to be mass produced exists 
now.  I'm wondering if the atmosphere can wait 15 years
for the internal combustion engine to be retired?
