MGX Minerals Inc (CSE: XMG, OTCQB: MGXMF) has unveiled more progress at its energy storage subsidiary ZincNyx Energy Solutions.
The latter has quadrupled the capacity of its fuel cell modules (stacks), it said in a regulatory filing.
ZincNyx has developed a modular storage system using zinc and air to store energy, which has none of the traditional high cost battery commodities such as lithium, vanadium or cobalt.
The battery is comprised of three main modules. These are a regenerator that uses electricity to charge particles of zinc, a fuel tank where the zinc particles are stored until needed, and a fuel cell module that uses zinc particles to generate electricity.
In simple terms, the fuel cell module consists of a stack of identical cells. In the original, each cell can generate 100 amps at around 1 volt, thus a stack of 12 cells was thus able to generate 100 amps at 12 volts, or around 1.25 kW.
But the latest advance doubles the area of each cell and enables up to 24 cells to be connected in series, thereby quadrupling the output capacity of a stack to 5 kW (200 Amps at 24 volts nominal).
'This development is a further illustration of the flexibility of the ZincNyx system,'' said ZincNyx president and chief executive Suresh Singh.
''Advances can be made to each component of the system without requiring simultaneous changes to the other components.
"In this case, the power generation capacity is increased without requiring simultaneous changes to the power regeneration capacity or the energy storage capacity.''
Last month, MGX revealed that ZincNyx Energy Solutions had struck a partnership with Digital Energy Corporation ahead of a potential rollout of the technology in New York city.
Systems integrator Digital will install the ZincNyx battery system at a demonstration site in the Big Apple.
