MGX Renewables Announces Production of Next Generation Cathodes for Zinc-Air Fuel Cell Battery

VANCOUVER, BRITISH COLUMBIA / September 3, 2019 / MGX Renewables Inc.

(“MGXR” or the “Company”) (CSE:MGXR FSE:0E9) is pleased to announce production of

next generation carbon based cathode for its Zinc-Air Fuel Cell Battery. To date the

Company has produced 300 cathodes for use in its initial mass storage battery systems.

Each 5kW fuel cell stack utilizes 50 cathodes. MGXR has developed proprietary and

patented fuel cell and battery technology and will continue to specialize in the design and

manufacture of cathodes in-house. The planned initial scale-up of cathode production is

for 36MW of annual equivalent capacity with a minimum storage of 8 hours or 288MWh of

storage followed by the addition of similar scale fabrication machinery as necessary. The

Company continues to develop a hybrid manufacturing strategy of leveraging its

proprietary designs utilizing fabrication partners for standardized components such as

injection molded pieces, with the most technically advanced and proprietary components,

such as the fuel cell cathode, being manufactured in house.

MGXR Energy Storage System

The MGXR ESS is a modular Energy Storage System designed to deliver power in the

range 20kW - 50MW and energy storage in the range of 120kWh - 1GWh over extended

periods of time. With the advantage of rechargeable zinc-air battery technology, the

system can be configured to support a wide range of discharge power, recharge power

and duty cycle requirements. Since the energy storage capacity of the system is

determined only by the size of the zinc storage tank, a highly cost-effective and scalable

solution now exists as an alternative to the fixed power/energy ratio of the lithium ion


Figure 1. MGXR modular Energy Storage System (ESS)


The MGXR ESS is based upon unique patented zinc-air battery technology. Energy is

stored in the form of zinc particles, similar in size to grains of sand. When the system is

delivering power, the zinc particles are combined with oxygen drawn from the surrounding

air. When the system is recharging, zinc particles are regenerated, and oxygen is returned

to the surrounding air.


The flexibility of the MGXR ESS enables it to service a wide range of applications. Typical

examples include:

  • Storage and smoothing current from renewable energy sources such as wind and

  • solar

  • Commercial, industrial backup replacing diesel generators

  • Industrial scale, on-demand power for peak shaving or standby

  • Grid scale energy storage for energy trading and arbitrage


The MGXR ESS is designed according to a modular architecture that enables a wide

variety of system configurations to be created from a small number of common

subsystems. Each subsystem implements a single element of the technology:

  • The Zinc Regeneration Subsystem (ZRS) provides the recharging function

  • The Fuel Storage Subsystem (FSS) provides the energy storage function

  • The Power Generation Subsystem (PGS) provides the discharging function

About MGX Renewables

MGXR has assembled an experienced team to execute the development and

commercialization of a dependable low-cost zinc-air battery. This mass storage system

offers both environmental and efficiency benefits. MGXR strives to meet the growing need

for secure and reliable power.

The sun doesn't shine all the time. The wind doesn't blow all the time. MGX Renewables mass storage batteries for the rest of the time.
