Fuel Cell Energy Storage System Design

What are fuel cells used for?

Fuel cells can be used in a wide range of applications, providing power for applications across multiple sectors, including transportation, industrial/commercial/residential buildings, and long-term energy storage for the grid in reversible systems.

Are hydrogen based fuel cells a good storage option?

Hydrogen based technologies can be developed as an attractive storage option for longer storage durations. But, common polymer electrolyte membrane (PEM) electrolyzers and fuel cells have round-trip system efficiencies of only 30–40%, and platinum and rare iridium catalysts are needed.

How is energy stored in a fuel cell?

Energy is, therefore, stored in the form of hydrogen. A battery of lower capacity is coupled with the fuel cell to handle transient loads. A parallel control algorithm is developed to switch on/off the charging and discharging cycle of the fuel cell and battery depending upon the connected load.

Can a fuel cell system be used in aircraft?

For this reason, a preliminary design of a fuel cell system and a hydrogen storage system for use in aircraft was developed in this paper. An existing regional jet with its mission profile was considered as a case study.

Can electrolyzers and fuel cells be used to design energy storage systems?

This is promising for the design of highly-efficient energy storage systems with electrolyzers and fuel cells. Current–voltage characteristics in electrolyzer mode using the AFC with 1.5 mm electrolyte-gap at different temperatures.

How does a fuel cell stack work?

Humidifiers. The fuel cell stack is the heart of a fuel cell power system. It generates electricity in the form of direct current (DC) from electrochemical reactions that take place in the fuel cell. A single fuel cell produces less than 1 V, which is insufficient for most applications.
