Lung-Inspired Fuel Cell Cuts Platinum, Boosts Efficiency

Scientists at the viagra costs Norwegian Academy of Science and cialis sales online Letters have designed a new fuel cell inspired by the bronchial structure of the lungs.  The new design requires less of the expensive platinum catalyst while also boosting efficiency.

The fuel cell features channels modeled after bronchial tubes that supply hydrogen and oxygen to their respective electrodes.  This system spreads the gases more uniformly across the electrodes, which boosts the cell's efficiency and creates greater surface area so that less platinum is buy viagra on line uk required.

Hydrogen fuel cells are still too cost prohibitive (among other things) for mass production and a lot of that has to do with the platinum catalyst.  This design is pretty exciting because it would lower the purchase of viagra cost of buying levitra without a prescription the fuel cell while also boosting output.  That's a win-win.

Neat idea - faster please

I'd much rather have a hydrogen-powered car than a battery-driven one.

But I think you meant to write "bronchial" structure.

Another interesting biomimetic example - Design inspired by nature.
The lungs gave inspiration also for carbon removal technologies.
