Metal-Air

  1. Zinc-Air batteries

Zinc-Air technology can provide a safe, environmentally friendly, and cheap option to store and deliver electrical energy for both portable and stationary applications. Zinc-air batteries have been known to be reliable, safe, inexpensive, and green. But there was always a problem to electrically recharge.

The development and application of rechargeable Zinc-Air batteries has been limited due to their low energy efficiency and low cycling stability. To avoid these issues Gnanomat develops metal oxide-graphene nanocomposites to be used as bifunctional electrocatalysts providing a substantial improved performance and stability during charge and discharge.

Gnanomat offers a versatile design and synthesis of electrocatalysts based on environmentally friendly elements getting a substantial improvement in efficiency, an improved performance and stability for the operation during charge and discharge and an eco-friendly solution for long-duration and rugged electrical energy storage systems.

  1. Alkaline Fuel Cells

Alkaline fuel cells consume hydrogen and pure oxygen, to produce potable water, heat, and electricity. They are among the most efficient fuel cells, having the potential to reach 70%. Despite AFC technology is one of the most developed fuel cell technologies in the 20th century, it has not been properly adopted by the commercial market.

However, portable applications are leading the development and adoption of other fuel cell technologies thanks to automotive sector companies as Toyota, Honda and Hyundai. But the AFC technology race to reach the industrial market is moving forward, and catalyst application is driven by energy efficiency and performance.

The trend is the substitution of the platinum by non-precious metal catalyst and Gnanomat is developing a solution, offering a low-cost and affordable platinum-free electrocatalyst material to be integrated in the MEA (membrane electrode assembly) of an Alkaline Fuel Cell.
