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.

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.
