## Scientific contributions

Emenike oversaw research under the guidance of the Laboratory of Industrial Electronics, Power Devices and New Energy Systems to build a gasification plant that produces synthetic gas from organic solid materials for use in electric power generation and other applications, generating 500KVA of electricity.
The Government of the Republic of Korea awarded three scientists (Okoye Kenneth Ejike, Emenike Ejiogu, and Matsui Sanchio) a patent in 2010 for their invention, which provides a fuel battery unit cell that can reduce in size and cost, as well as an array of fuel battery unit cells, a fuel battery module, and a fuel battery system.
Also, Okoye Kenneth Ejike, Emenike Ejiogu, and Matsui Sanchio were awarded a patent by the United States of America in 2013 for their invention that offers a fuel cell unit, fuel cell unit array, fuel cell module, and fuel cell system that can reduce size and prices.

## Membership and fellowship

In 1996, Emenike became a member of the New York Academy of Sciences. He was also nominated as a member of the Institute of Electrical and Electronics Engineers in 1992, a member of Japan Institute of Electrical Engineers in 1994 and a member of European Power Electronics Association.
