摘要： To provide a fuel cell system of dead end type capable of generating power with high efficiency. A fuel cell system 1 has a fuel cell 2 and pressure controlling means 9 that controls the pressure of a fuel gas. The fuel cell 2 is operated in a state where a channel 10 for a fuel off-gas is closed. When a predetermined time elapses, the channel 10 is opened for purging. The pressure controlling means 9 sets the pressure of the fuel gas at P1 from a point in time immediately after purging to a time t1 and sets the pressure of the fuel gas at P2, which is higher than P1, when the time t1 elapses.

摘要： The procedure of the invention successively obtains an estimated value of amount of liquid water in a fuel cell during operation in each specified period by the following steps (a) to (d), thereby improving the detection accuracy of the water condition inside the fuel cell. The step (a) obtains a previous estimated value. The step (b) obtains a drainage rate that represents an amount of liquid water discharged from the fuel cell per unit time, based on the previous estimated value and a value representing a current flow rate of a reactive gas in the fuel cell. The step (c) multiplies the drainage rate by a period of obtaining the estimated value, so as to calculate an amount of liquid water discharged from the fuel cell for a specified duration. The step (d) determines a current estimated value, based on the amount of liquid water discharged from the fuel cell for the specified duration.

摘要： A fuel cell battery (2) has a structure in which a plurality of cells are stacked and in-series connected. The cells include a cell (15), and one or more cells (16) of a cell stack (11). Hydrogen that has entered the fuel cell battery (2) from a channel (12) is supplied to each cell through a supply manifold (13). After the amount of hydrogen needed for power generation is consumed, gas is discharged as a fuel off-gas into a discharge manifold (14), and then flows into the cell (15). This prevents impurities contained in the fuel off-gas from being accumulated in the cells (16), and causes the impurities to be accumulated in the cell (15). Thus, variations in the amount of power generation among the cells can be restrained in a fuel cell battery system that employs a dead-end method.

摘要： In a fuel cell stack, each separator is constructed by sequentially stacking and joining an anode-facing plate 42, a middle plate 43, and a cathode-facing plate 44. The anode-facing plate 42 has multiple hydrogen inlets 422i arranged in a two-dimensionally distributed manner on its plate surface. This arrangement effectively prevents a decrease of power generation capacity due to local accumulation of water produced in the course of electrochemical reaction for power generation or other impurities on the surface of either an anode or a cathode.
