A New Way To Make Water, And Fuel Cells

Roland Piquepaille writes "You probably know that it is easy to combine hydrogen and oxygen to make water. After all, this chemical reaction is known for more than two centuries. But now, researchers at the University of Illinois at Urbana-Champaign (UIUC) have discovered a new way to make water. As states the UIUC report, 'not only can they make water from unlikely starting materials, such as alcohols, their work could also lead to better catalysts and less expensive fuel cells.' But be warned: don't read the technical paper itself. It could win an obfuscated contest — if such a contest existed for scientific papers." Yet another advance in fuel cell technology; we discussed a different one just the other day.

    Shouldn't it be the other way around?

    An obfuscated contest or a contest for obfuscation? The fomer would be difficult to figure out, while the latter would reward entries that are difficult to figure out.

    No one in the state calls it UIUC, except for University of Illinois at Chicago students and alumni who get upset when you call it U of I. Every one else just calls it Illinois. It confuses everyone else when its referred to as UIUC.

      Actually "everyone else" might just be defined to be people who aren't in your state... last I checked there were more people not from Illinois than those from Illinois. (And if you have to pick a segment to confuse, I'd think you'd want to pick the ones who are near the place and can probably figure it out.)

      Good to know either way, but whether you like it or not, the majority of folks know it best as UIUC. Sorry that you're so well known and all. :)

      Also, if they don't want to be known as UIUC, perhaps a change of domain name is in order...

      We have tonnes of powdered water here every winter,and amusingly enough, licking it is one of the ways to restore it to liquid water. Just add a label to 'add heat' and you're back in business.

    The reaction rate of oxidizing hydrogen or even many alcohols isn't a problem with the catalysts in current use, the porblem is that the catalysts are based on platinum, rhodium etc.. which are extremely expensive. The catalyst in this case is based on Iridium which is also very expensive, if not more so than Platinum. Lcohols are not an unusual starting material for making water and giving off large amounts of energy in an oxidation reaction. Methanol for example, in contact with Platinum in air will oxidize to formaldehyde and water releasing enough heat to eventually cause the platinum to glow red. This is in fact used to great effect in certain fire-starting mechanisms.

      Right, alcohol fuel cells already exist.

      My reading of the blurb leads me to think their apparent contribution is finding an iridium based metal hydride that catalyzes both the oxidation and reduction sides, which I never thought about and didn't know platinum couldn't do. Your example above leads me to think it can so I'm wondering what this is really all about.

      Also we have a new reason not to RTFA. The summary forbids us from doing so.

    Er... Water is pretty much the side product of almost any reaction. For example, you may have heard that ethanol burns relatively cleanly. Translation: Ethanol -> Carbon dioxide + Water
    This has almost never not been known.

  7. Free Energy by Doc+Ruby · · Score: 3, Informative

    All these chemicals are just storage media for energy released by the fuel cells. Where is all that alcohol supposed to come from, Russia's motherlode of vodka wells?

    Making the alcohol consumes the very energy released by the fuel cells along with water. If the alcohol is fermented vegetation, that bacterial process consumes some of the energy to process the higher-energy sugars and carbohydrates in the vegetation. The vegetation is the key, because it converts the actual source of energy, sunlight, into those sugars. But by the time the alcohol hits the fuel cell, already over 95% of the sun's energy is lost in other processes before the final 50-80% max efficiency is applied to the usable 5%.

    This is about "generating power in a fuel cell".

    Poor Zachariah Heiden made some comment that included the partial sentence "unconventional metal hydrides can be used for a chemical process called oxygen reduction, which is an essential part of the process of making water", and all the context got thrown away.

    The actual paper seems to be "Homogeneous Catalytic Reduction of Dioxygen Using Transfer
    Hydrogenation Catalysts".
