Next-Generation Air
Cathode Materials
Product Availability
We are currently offering a series of
electro-catalysts for our customers and
partners in a range of air cathode
applications. These air cathode materials
are produced from inexpensive precursors
using a process that is scalable and
economical. The material can be provided
as raw powder or in a packaged GDE form.
pH Matter, LLC is providing viable commercial
catalyst solutions in a number of emerging
markets, including metal-air batteries, fuel cells,
and industrial electrolysis.

Electro-catalyst Materials for Air Cathodes
Durability Comparisons
pH Matter has developed a patent-pending nextgeneration oxygen reduction reaction (ORR)
catalyst materials for air cathode applications. The
advantageous properties of this material include:
 High activity for the ORR in acids or bases
without the need for metal catalysts.
 Exceptional durability in strong acids, strong
bases, and during frequent voltage cycling.
 High surface area and electrical conductivity.
