Q:i am doing a huge project on them for school and i have to write a 5-7 page report on them and construct a model running on fuel cells. i dont know how i am going to do it. i am interested in this topic. and im not sure what key points to go over i my essay.please help

type in: what are fuel cells? It will take you right to it.

Q:Why is the fuel cell fuel put the negative?

The cathode, the anode is named according to the redox, the positive pole, the negative pole is named according to the current direction. In the literature on the study of battery materials, the cathode and anode are generally used, and the positive and negative electrodes are commonly used in terms of circuits.

Q:And which auto-maker is going to be the first to take advantage of rising gasoline prices and actually manufacture Hydrogen powered cars?

a okorder

Q:How would this be determined? What variables affect the volume of water produced per watt/kilowatt? If a cell is loaded heavily, does it produce more/less/same amount of water per watt than if it is lightly loaded?

Q: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!

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

Q:I heard its from fuel cells? Even heard that the astronauts carry enough water for themselves? Please and thanks guys

They don't bring a whole lot with them, actually. It is very expensive to bring too much. Most of their water is recycled while they are out there. Their urine, their sweat, everything. There's a filtration system on the shuttle that recycles all of the moisture that they emit. -------------------------- I don't get the thumbs-down. Somebody show me where I'm wrong, because I've listened to interviews of NASA employees and astronauts who have explained the same thing. If I'm incorrect, I apologize, but I've heard this several times.

Q:i cant remove the fuel cells from the wall now. i saved my game already, i think im screwed

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:i built my cell from what i learned on you-tube. just a few new ideas i added. it makes a large amount of gas burns real well, off the bubbler. im looking for some other smaller type of anti flashback, smaller than the bubbler. another thing is that ive only hooked it up on my 95 dodge dakota, like maybe 45 min. fear may cause some harm to the truck.? what do i do for the sensors/computer? any suggestions?please dont respond, if you are just going to speak in a series of clicks and grunts about something you have no idea about, doesnt work.im ase sertified, have been since 1996, also work as a mechaic in a shop. so go to the food drink category and asnwer something you know, like how to make toast or something. thank you.

i now found someone thats knows it works,i too have it on my 86 ford.truck. wasnt to clear on your question.do you want to build smaller anti flashback device.i used 10 inches of 1 inch p.v.c. pipe,two end caps,filled the p.v.c. with copper dishwashing scrubber,drill hole in each end of caps .insert your vaccum lines.i expoxed them in.i hope this helps. buz.

Q:Compared to gasoline, how expensive are they?

Back when a barrel of oil cost $20, we were told that fuel cells could not be economically competitive unless and until the price of oil rose to about $100 a barrel. So where the hell are they? Who's keeping the technology under wraps now? I wonder.

Q:Are fuel cells out yet, if not when will they be out.If so were are they available?A link to a source will be VERY HELPFUL!!! THANKS

I saw a PEM fuel cell years ago. It was about the size of a U Haul trailer. Because of the cost, it technically wasn't a good deal. People are still trying to make fuel cells that are small enough and safe enough to use in laptops and other portable electronic gadgets. That hasn't been going very well.
