The Power Output of H-Bat is determined by the
Voltage of the Cell and it’s Current Density. Since the
Voltage is limited to 1.2V because of the breakdown of
water at higher voltages, it’s the gains in the Catalytic
Current Density that determine the gains in the Power
Output.
Future Milestones for H-Bat's increased Power Output and Energy Storage Capacity
Power Output Energy Storage Capacity
1. Internal H2 storage inside H-Bat
The Energy Storage Capacity is dependant on the
amount of H2 fuel stored in the battery. The H2 fuel is
stored in a non-gaseus form in the micro cavities of the
fuel storage material. The more %H2 we can store in
the micro cavities by weight of the storage material,
the more energy the battery stores.

2. External H2 storage, full pack
Alternatively an external H2 fuel pack can also be added.
This can be H2 in a non-gaseus form, bound in a micro
cavity material. Compressed H2 works just as well.
Each milestone has different challenges. Below the
technical challenges to be solved at each level.

Each milestone has different challenges. Below the
technical challenges to be solved at each level.
Milestones
Milestone P1
Quality Production Process should be able to easily yield
0.250 A / cm2 at the cathode side with the materials currently
used in the MVP
Milestone P2
Improvement of the conductivity of the carbon layer will bring
us into the range of 0.300 A / cm2 at the cathode side
Milestone P3
Improvement of the conductivity of the polymer will bring us
into the range of 0.500 A / cm2 at the cathode side
Milestone E1
Quality Production Process should be able to easily yield
1.2% storage of H2 by weight with the materials currently
used in the MVP
Milestone E2
Further improvement of the purity of the used material in the
MVP and high quality production process will bring us into
the range of 1.5% storage of H2 by weight
Milestone E3
Creation of a new type of H2 storage material as a
combination of currently used materials and metal alloys will
bring us into the range of 2.0% storage of H2 by weight.
Milestone E4
Creation of a totally new type of H2 storage material at
potentially higher operating temperatures has the potential to
bring us into the range of 3.0% storage of H2 by weight.
