"One of the major challenges to developing affordable hydrogen fuel cells has been storage. Hydrogen is explosive and requires costly containers to hold it safely.
But recently, scientists have shown that formic acid is a good candidate for storing hydrogen.
The common industrial chemical—also the stuff of ant venom—is stable and inexpensive.
One molecule of the acid is made of five atoms, two of which are hydrogen atoms. But splitting the formic acid to release hydrogen and produce electricity requires a lot of heating and processing.
Except that Professor Colin Oloman of MVTG has done it directly in the MVTG-MRFC fuel cell recently demoed in the Spark-E-Vehicle at the Marcum conference in May in NYC, to produce up to 95% efficient electrical power directly from the formic acid, with no reformer, no heat and no PEM membrane or bipolar plates that are about 70% of the cost of today's cheapest fuel cells.
