Abstract
A fuel cell system and a method for controlling the same. The system and method employ a fuel cell stack that generates electrical power by electrochemical reaction of a fuel gas and an oxidant gas, a total generated electrical energy computation device that computes a value pertaining to the total generated electrical energy as the sum of the electrical energy generated by said fuel cell stack from start-up of the fuel cell system, and a residual water volume estimation device that estimates the residual water volume left in the fuel cell stack based on said value pertaining to said total generated electrical energy computed by said total generated electrical energy computation device.
