Q:Mass of a fuel Cell in chem?
A fuel cell is closed, so the Law of the Conservation of Matter applies. The mass can't change unless something leaves or enters into the fuel cell, which doesn't happen. All sorts of reactions might or might not happen, but as long at the system is closed the total mass stays the same.
Q:What is the battery used for in a hydrogen fuel cell car?
Most fuel cells do require energy to start the reaction - but it is just initially to generate some heat. You could do this with a small battery to start it up, so the large batteries are not necessary for that. What they are there for is because fuel cells are good at providing a very consistent amount of electricity - they aren't very good at providing big bursts of electricity all at once, and you can't use regenerative breaking to recharge a fuel cell. So instead, you have a battery pack that is much smaller than the battery pack that would be used on a car like the Leaf, and instead you have a fairly small battery pack like the one used in a Prius or some other hybrid car. Personally, while I certainly like hydrogen fuel better than gasoline, it is ultimately just a stop gap until we can drive pure electric vehicles. Because of that, and because fuel cell technology is very expensive, and because we have ZERO hydrogen infrastructure, I'm going to skip them and get an all electric (Leaf) instead. :)
Q:Confirm the statement that oxidation of 1.0 L of methanol to form CO2(g) and H20(l) in a fuel cell will?
There is a missing number: you need the heat of combustion of methanol, which is about 80,000 BTU per gallon. If you convert this to metric units, and assume (because of the reference to the fuel cell) that all the heat is transformed into electricity, you can determine the amount of electricity created. The gotcha is that fuel cells are pretty much limited to hydrogen at present; if they could burn methanol or ethanol (or better yet, alkanes such as gasoline), it would be better as any of these fuels are much more easily handled than is hydrogen.
Q:Is it true that hydrogen fuel cell produce unlimited electricity?
Electricity, because the means of producing it is already established on a mass scale. Hydrogen fuel cells are still relatively new, and haven't seen mass production on a level that would reduce costs. Electricity is virtually free today, while hyrdrogen still has a cost to process.
Q:What are the environmental consequences of all that water vapor from hydrogen fuel cells?
None. This emission is environmentally benign. That's the commonly used jargon in the fuel cell industry. This water is recyclable in nature. It goes into the atmosphere, then returns as rain into the ocean, rivers, lakes, etc. No damage to the environment - long term or near term. On another note, for lower temperature fuel cells, the water is given off as a liquid. For higher temperature fuel cells, the exhaust can be used for heat recovery purposes. So it actually serves some engineering purpose.
Q:power density with reference to a fuel cell?
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.
Q:why is hydrogen fuel cell technology not viable?
Come up with hydrogen fuel-cell solutions these days.
Q:does anyone know anything about fuel cells?
type in: what are fuel cells? It will take you right to it.
Q:metroid prime - i used a fuel cell in the wrong room in valhalla. i cant find any more, do i have to start ove
Valhalla actually doesn't seem to do much. Just ignore it and do everything else until you gather all the fuel cells. There's plenty of them in the game, no such thing as using it in the wrong room.
Q:anything about alternative fuel sources?
In racing they use Methanol (wood alcohol) because of the high octane rating needed for high compression engines producing 500+ H.P. The only drawback it is corrosive to some metals and o rings, and you need 2 times the amount vs. gasoline. Hope this may help you. See Wikipedia on methanol!
