New Tech Could Bring Fuel Cell Powered Electronics

MIT just announced that its engineers have improved the power output of one of their fuel cells, by over a startling 50%. What’s even more surprising is that the new material that makes this increase in efficiency possible, is actually cheaper than conventional methods.

The research was done on united pharmacy cialis canada direct methanol fuel cells (DMFCs), which utilize methanol as a fuel rather than the more commonly known hydrogen cells. Among the generic cialis 10 mg without prescription advantages of using methanol over hydrogen is that being a liquid, and not highly volatile, it is easier to store and real cialis without prescription transport, it has a high energy density, and it’s easy to refuel, there is no specialized fuel station necessary, just pump (or pour) and go.

Traditional DMFCs have a membrane made of Nafion, an expensive material, and one that is also permeable to wow look it cialis india methanol, which means you waste some of your fuel without getting anything out of generic cialis forum it. So the team at MIT designed a new nanomaterial, using a technique known as layer-by-layer assembly, to create an alternative. “We were able to tune the structure of [our] film a few nanometers at a time,” says one of the researchers. This new film, which is cheap viagra on line cheaper to produce, is also 2 orders of magnitude less permeable to methanol, thus conserving fuel and greatly improving power output.

This advance could play a big role in portable electronics (such as the LG latop pictured). We recently saw that DMFCs are already on the market, and coming soon for cameras, though they are a bit bulky, but this new technology could halve the size of the units, making them more attractive for compact portable electronics.

The researchers are now looking at seeing whether their membrane could be used in improving the efficiency of photovoltaics. We certainly hope so.

Methanol is not safe

Do we really want our children to be topping up their fuel cells with methanol? It is an horrible poison.
