Oxygen mix promises to increase fuel cell performance
Quick blurb from the article:
Quick blurb from the article:
Awesome to see progress in R&D of efficient fuel cells. They've been the "next big thing" for some time, and announcements like this give me hope that we'll see FCV's on the roads... at some point, at least.PORTLAND, Ore. ? Supercharging fuel cells by premixing the fuel with oxygen holds out the promise of superslim fuel cells that can be manufactured on a printing press.

Whereas those traditional designs measure about 2 mm thick, according to Generics, the CMR fuel cell eliminates the metal flow-field plate completely and uses a thin, perforated polymer membrane.
To keep the fuel and oxygen separate, traditional fuel cells put metal flow-field plates between adjacent cells. One side of the flow-field plate supplies fuel to the anode of the next fuel cell, while the other side supplies oxygen to the cathode of the previous fuel cell. The anode and the cathode are separated by a solid polymer membrane to segregate the fuel and oxygen.

?The membrane material in a typical fuel cell is 100 microns thick-at a cost of about $300 per square meter. But our perforated membranes only need to be about 1 micron thick,? Priestnall said. ?The cost of membrane material in a normal fuel cell is over $500 per kilowatt. We have brought that down to $15/kW.?
