Sony has a developed a prototype of an ultra-small fuel cell system that contains a newly developed platinum alloy.

The electrode catalyst is made of the new platinum alloy, according to reports from Tech On, and Sony has reportedly filed for patents on the new system, as well as materials and other aspects of the technology.

The new development is the first time that Sony has included a rechargeable battery, control circuit and other elements into the same system.

Previously, the firm had only been involved with evaluation results for solid polymer electrolyte membranes using fullerene, membrane electrode assemblies.

Sony's material laboratory said: "We have been aiming for a system that can be put into mobile gear."

The firm said it had reached a stage where it could explore commercial design.

The prototype will use a direct methanol fuel cell and will operate with a peak output of 3W - enough to support a mobile phone - the firm said.
