Hearing aids running on methanol

In just a short time, hearing aid batteries could be replaced by a drop of methanol.

Danish scientists are working on replacing the existing batteries in hearing aids with easily rechargeable fuel cells which run on methanol.

”We have come further than we ever could have hoped when we started this project of designing methanol-based batteries which can replace the traditional zinc batteries in hearing aids today”. That is what Leif Højslet Christensen, head of the Danish Technological Institute, and head of the project, says.
