NaBH4 (aq) + 2 H2O 4 H2 + NaBO2 (aq) + heat
An energy-dense water-based chemical hydride fuel
Proprietary catalyst induces rapid H2 production
High purity humidified H2
Borate can be recycled into NaBH4 or can be disposed of
Exothermic reaction requires no heat input
1. Borohydride Fuel is pumped or moved from a tank through a chamber containing MCEL’s proprietary catalyst.
2. The fuel is converted into pure hydrogen, water vapor, and borate (NaBO2).
3. The temperature and humidity of the hydrogen stream are adjustable. Humidified hydrogen is sent to the fuel cell.
4. The fuel cell creates power and water. This water can be recycled within the system. Allows for higher fuel concentrations.
