"I can't remember where I read it NL but if I remember correctly a fuel cell is typically 110-120kg in mass. Graphite makes up 75-85% of that mass so about 90kg of Albany graphite per fuel cell." VH
ValuHunter is correct corroborated by ZEN Presentation "90 Kg Graphite per Cell" referencing I believe Ballards PEM Fuel Cell which has these stats for PEM,
"The total number of plates in a stack is therefore 740: 369 active cells * 2 plates per cell + 2 coolant-only plates * 1 stack14. Because each system contains 740 bipolar plates, there are hundreds of thousands of plates needed, even at the lowest production rate. This means that bipolar plate mass-manufacturing techniques remain appropriate across all production rates. " Ballard
Other Stats,
Li-ion – Smart Phones 15 grams, Slide 7 (for ref: Apple sold 74.5M iPhones last qtr as of 2015-01-27, 30,000 every hour)
- Auto 85 kWh 100 kg Slide 7
o Natural Anode $15 kg Slide 8
o Synthetic Anode $20 kg Slide 8
- Bi-Polar Plate 90 kg Graphite /Cell Slide 9
- Pebble Bed Reactor
o Start-up 3000 tonnes
o 1000 tpa for a 1 GW Reactor
- If Production is 200,000 PEM Vehicles/year, 148M Bi-Polar Plates would be required (740 plates/Fuel Stack/Vehicle based on 369 active cells/stack)
- Amount graphite/plate ???
- Cost of Carbon Black Graphite ???
90 kg Graphite/ fuel cell / 740 Bi-Polar Plates
= 90,000 g / 740
= 121.62 g per Bi-Polar Plate?
90 kg Graphite/Fuel Cell x 200,000 Auto’s/year
= 18,000 tonnes Graphite of yearly production
ZEN news confirms making great strides in proving Albany Graphite for usage in Fuel Cells, to displace the more expensive Synthetics with better comparable characteristics.
LiB is overdue and this sector could be big news too, before this year is out, cheers, Mark |
