The DBFC (Direct Borohydride Fuel Cell) is the major Borohydride application of MERIT Ltd.. Different to other fuel cells our DBFC uses Borohydride resolved into an aqueous solution as fuel. The method of using Borohydride instead of gaseous hydrogen, has many advantages. First of all the storage problem has been solved. For mobile applications no special devices such as dangerous high pressure chlinders or an energy consuming apparatus which chill down to liquid hydrogen state are needed.
Borohydride fuel is safe, operates at low temperature, contains a high H-capacity of hydrogen and is as easy to handle as gasoline. Furthermore our DBFC has a higher performance and is cheaper than any other fuel cell.
As described in our "BH4- as a hydrogen storage material" section, the borohydride complex ion makes it possible. It releases 8 electrons instead of just 4 for the electricity production. This fact leads to a higher overall performance of our DBFC.

Evaluation System for DBFC test
This figure shows a scheme of a DBFC test system. Our researchers experiment with new fuel cell stacks and collect important data while using such kind of system. You can see a picture of the same set up in our DBFC application and prototype section.
