Description/Abstract

Fuel cells utilizing the direct and indirect oxidation of
borohydride ions have been described. Direct borohydride
fuel cells are inherently more efficient than IBFCs;
the DBFCs can produce energy densities comparable to
those of methanol and oxygen–hydrogen fuel cells. The
DBFC still presents a number of technical challenges
such as borohydride ion crossover and the need for more
selective anode materials and improved anionic membranes.
The IBFCs use the well-studied MEA that is fed
with high-purity hydrogen produced from the efficient
hydrolysis of sodium borohydride. The main problems in
this cell are removal of borohydride oxidation products,
reuse of catalyst, and heat and water management
