Gorivne celice- kaj lahko pričakujemo v prihodnosti

Za maturo imam projektno nalogo- gorivne celice in trenutno sem že pri koncu, imam pa namen še predstaviti celice v prihodnosti, oziroma napovedi za prihodnost (moč, velikost, shranjevanje vodika, izkoristek,...) Ima kdo kašen pameten link? Nekaj sem že iskal primerke ultra majhnih celic, potem sem našel še nekaj primerov iz avtomobilskega sveta,... Ima še kdo kašen pametno povezavo?

Zgolj o vodiku (in avtomobilizmu).

Let's see.. Maybe gasoline is the fuel of choice ... because of it's volumetric energy density? And liquid hydrogen makes good rocket fuel because of its gravimetric energy density?

Hydrogen. Embrittles its container (explodes pores in metals - forms brittle hydrates) is one of the most dangerous gases to handle - explosive from 4 - 96% concentration. You would have to store vehicles outside - no tunnel use etc. Besides the most economical way to produce hydrogen is from oil - Best way to store hydrogen is as gasoline - as there is more hydrogen in a gallon of Gasoline than in a gallon of liquid hydrogen. In any article you read about hydrogen, it is a good idea to replace the words "hydrogen economy" with "boondoggle" to get a clearer meaning. We have moved some comments to the discussion area as it appears that some people think we will find a new 'brand' of hydrogen that is safer.

There is a good and safe way to store hydrogen - start out with a chain of carbon and attach the hydrogen to this chain - as a liquid this will be hold more hydrogen than liquid hydrogen. This liquid could be distributed to underground tanks and pumped directly into a vehicles fuel tank. This liquid is called gasoline.

Kako je z ostalimi gorivi za celice ne vem točno, ampak tukaj si lahko prebereš.

Še en link.



"Yes, my friends, I believe that water will one
day be employed as fuel, that hydrogen and
oxygen which constitute it... will furnish an
inexhaustable source of heat and light...Water
will be the coal of the future"

- Jules Verne, The Mysterious Island,1874.

He was wrong.
Water will never be a fuel, only a byproduct of energy production. Link.

ja, predlagam da razložiš, zakaj je vodik slab kot nosilec energije in je bolje se furati direktno na nafto (in je ne pretvarjati, ker vmes ni drugega kot izguba) ali pa na elektriko (kjer so problem trenutno baterije) in da so gorivne celice bolj ali manj nesmiselne kot vir energije).

To sem že naredil. Drugače pa hvala za linke ene par zadevic bom še dodal.

Sem našel še en zanimiv link: http://www.newscientist.com/article/dn1...

Edit: Ve kdo, kje bi se dalo kupit kašno gorivno celico (ali pa model) za majhne pare?

Lahko celo priložiš modelček avtomobila na gorivno celico.

prihodnost gor. celic bo taka: jst osebno bom nardil nizkotemperaturne, visokoučinkovite (+80%), ter majhne in kompaktne s pogonom na lahke ogljikovodike (bodisi plinaste bodisi tekoče (lahek bencin). če se pa bo trend zasukal pa morda tudi na alkohol in ogljikove hidrate.
in praktično vsi avomobili jih bodo imeli. tako bo. pa ne pozabi omenit da me poznaš

samo v glavi. ampak že ti so zelo učinskoviti. kako bodo šele tisti, ki jih bom dejansko naredil!!

Uff, komaj že čakam

tudi jaz!
