Document Type and Number:
Japanese Patent JP2007220425
Kind Code:
A
Abstract:
To provide a fuel cell system capable of avoiding circulating pump damage at low temperature, and improving system efficiency.
This fuel cell system comprises a fuel gas circulation system with a circuit for returning a fuel offgas output via a fuel cell to the fuel cell, and a circulating pump for forcefully feeding the fuel gas in the circuit; and a controller for controlling circulating pump activation. The controller prevents the circulating pump from being activated at a prescribed low temperature.
