Abstract
The invention detects quickly and with high precision abnormalities in fuel cells. In a method of detecting abnormalities in a fuel cellcomprising a plurality of unit cells that generate power by supplying hydrogen gas to an anode and supplying air to a cathode of each unit cell, the abnormality in the fuel cellis detected based on the speed of the decrease in the cell voltages after stopping the fuel cell, i.e., after stopping the supply of the reacting gases to the fuel cell.
