Background: Improvements in fuel cell technologies for automobiles have been actively pursued by researchers globally over the past decade. In particular advances in polymer electrolyte fuel cells (PEFC) have been vigorously pursued. Primary challenges in the field of automobile fuel cell technologies have included component costs durability sufficient ORR reactivity and adequate catalytic power-generating performance. Therefore there exists a present market demand for polymer electrolyte fuel cell technologies that produce higher oxygen reduction reaction (ORR) and subsequent improved power-generating performance. Technology Description: University of New Mexico and Daihatsu Motor Company researchers have developed a fuel cell technology comprised of a first catalyst containing a first transition metal and polypyrrole and a second catalyst containing a second transition metal and a porphyrin ring-containing compound so that the mixing ratio of the first catalyst relative to 100 parts by mass of the total amount of the first catalyst and the second catalyst is more than 10 parts by mass and below 90 parts by mass. The oxygen reduction reaction in the oxygen-side electrode (cathode) is enhanced thus improving fuel cell performance. Applications: 1) Improved oxygen reduction reaction (ORR) 2) Increased power-generating performance 3) Automobile applications

Benefits:

The oxygen reduction reaction in the oxygen-side electrode (cathode) is enhanced thus improving fuel cell performance.
