There are five primary types of fuel cells—alkaline, phosphoric acid, proton exchange membrane, molten carbonate, and solid oxide. Different fuel cell types are suited to different applications.
Problems caused by these harmonic currents include overheated transformers, switchgear and wiring; random circuit breaker tripping; and reduced useable system capacity.
This article is one of a three-part series of articles that is intended to inform those involved with electrical installations and inspections about fuel cell technology.
A fuel cell is an electrochemical device that combines hydrogen and oxygen to produce electricity, with water and heat as the by-product.
The installation of electric vehicle systems is covered by Article 625 and is the responsibility of code making panel 12 (CMP-12).
