補償を行う。。(]-) EXAMPLE The flilJ control system according to the present invention will be explained with reference to the case of two air-cooled fuel cells shown in FIG. Individual batteries (1
1 (1), as is well known, a battery reaction is performed using air (for reaction and cooling) supplied by each blower (21 (2+) and reformed hydrogen gas from a reformer (not shown). In this case -
each? The high temperature air discharged from the lj pond is transferred to each damper (3) (3
) is distributed to the exhaust path (4) (4j) and the circulation path (5) (5), and the low temperature air corresponding to the exhaust air is distributed to the outside air intake path +6 + [from (3) introduced, 42
It is supplied to each battery together with the air distributed to the i circulation path. Individual in this way? :i. Cool the pond and compensate for the oxygen partial pressure. .

定になるよう制御される。The DC output of each of the parallel connected ponds (1) (1) is converted into three-phase AC by the impark (7), and most of it goes to the load (L), while a part of it (approximately the battery output) 10%) is
Inverter for each prower +81 (via the prower (2)
) and (2) respectively. In general, each battery is connected to its temperature detector (91 (91) by the signal from the damper (4) +4+ and the blower-dedicated inverter (51 (5)
By adjusting the supply air temperature and air amount, the temperature of each battery is controlled to be substantially constant.

Ｖ−１カーブを一致させる。The principle of the present invention is to set the temperature of each battery so that equal current flows through each battery. In other words, for 1 hour, batteries with a large current value should be lowered in battery temperature. [1. For batteries with a small flow f1h, the battery temperature is controlled to be raised to match the V-1 curves of the individual batteries.
