Fuel cells works, hydrogen, Toyo Tanso Launches New Catalyst For Fuel Cells

Toyo Tanso Co., Ltd.  and N.E. CHEMCAT Corporation have been working together on the development of electrocatalysts for fuel cells. In order to meet the growing needs of the expanding fuel cell market, Toyo Tanso has commercialized a new platinum-loaded electrocatalyst for the fuel cell market, CNovel™ “MH-18-PT50”, which will be available as a reagent from April 1, 2021.

Fuel cells are currently used in applications such as stationary (Residential) and FCV. With the continued exploration of hydrogen as a clean source of energy, further improvements in performance, lifespan, and costs are needed for expanded use of fuel cells. This is resulting in the increased need for effective use of platinum catalyst, a key material for fuel cells.

CNovel™, a product of Toyo Tanso, is a porous carbon powder material with a unique pore structure known as interconnected pores. In order to improve the electrochemical properties of the material, a unique heat treatment technique has been applied to enhance its functionality, and it has proven to be a high-performance catalyst support for fuel cells. [Fig.1]

N.E. CHEMCAT possesses advanced catalytic technology and has succeeded in producing highly functional catalyst particles by optimally dispersing and loading platinum nanoparticles into the pores of CNovel™, taking advantage of its unique structure. [Fig.2]

We are pleased to announce the availability of reagents to facilitate the use of these highly functional catalyst particles.

N.E. CHEMCAT will continue to work with Toyo Tanso for the further improvement and to stabilize the supply of CNovel™ -based fuel cell catalysts in anticipation of future growth in demand.

This product, CNovel™provides higher catalytic performance and higher durability compared to the conventional catalysts support (e.g., carbon black). [Fig.3, 4 and 5]

It also contributes to lowering the cost of fuel cell systems, as the catalyst are dispersed and arranged optimally, and the performance can be stabilized even with a lower amount of catalyst than conventional products.

Toyo Tanso’s new reagent allows users easier to obtain the platinum-loaded CNovel™ products, MH-18-PT50 and the advantages the products offer.

Definition of Terms

Inter-connected pores: A structure consisting of mesopores (2 to 50 nm in diameter) connected to each other

Major Applications

Electrocatalysts for fuel cell, platinum-based chemical catalysts

Main Features and Advantages
