I have searched wikipedia and i know that power density refers to the amout of power that can be generated per unit volume. but in the case of a fuel cell, what exactly is the 'volume' in question? formulae will help a lot! thanks!
together because it must be technically conceivable to construct a nuclear powered plane it would be thoroughly impractical. with a view to hold in basic terms the flight group you will possibly in all risk finally end up with an plane the dimensions of a 747 in basic terms to contain all the kit necessary to function the reactor thoroughly. So, the only benefit to it could be the means to theoretically fly for years with out landing. yet you will possibly could rotate the group, resupply the foodstuff and water and carry out maintenance. And to do those issues, you may land. so which you have outfitted an exceedingly high priced plane that has very constrained makes use of and which might in all risk be unlawful to fly over any populated section in basic terms in case of a crash. according to risk conceivable, in basic terms no longer properly worth it.
I'll guess about 5000 watts per cubic meter 4000 watts per cubic yard. That includes minimal axillary equipment, but not the batteries, super capacitors, hydrogen storage or manufacture. To be competitive for vehicles the volume needs to be reduced considerably, or the power density increased. Neil
