Embodiment Construction

[0017] Embodiments according to the present invention will be described with reference to the drawings. However, the size and ratio of each component shown in the drawings may not correspond to the entity.

[0018] (Example)

[0019] First refer to figure 1 A description is given of the fuel cell system 1 according to the embodiment. figure 1 is an explanatory diagram showing a schematic structure of a part of the fuel cell system 1 according to the embodiment. figure 1 Parts of the fuel cell system 1 , in particular surrounding the fuel cell stack 3 and the coolant circulation channels 17 , are shown. For this reason, there will be no figure 1 Components that will be described below are shown in . In addition to various moving objects such as vehicles, ships, airplanes, and robots, fuel cell systems can also be installed in stationary circuits. As an example, a fuel cell system 1 installed in an automobile will be described here. The fuel cell system 1 includes a solid...

Abstract

A fuel cell system (1) includes: a fuel cell (2); a coolant circulation passage (17); a radiator (18) installed on the coolant circulation passage; a water pump (23) configured to circulate a coolant in the coolant circulation passage; a flow dividing valve (19) configured to control the flow amount of the coolant flowing the radiator; a fan (18a) configured to transport air to the radiator; and a controller (21) that, when a first prescribed period elapses in a state where a temperature of a coolant is equal to or more than a first prescribed temperature and an opening degree of the flow dividing valve makes the flow rate of the coolant flowing into the radiator equal to or more than a prescribed flow rate, gives a priority to the rise in a driving voltage of the fan over the increase in a flow rate by the water pump, and when a second prescribed period elapses in a state where the temperature of the coolant is equal to or more than a second prescribed temperature after the driving voltage of the fan is raised, increases the flow rate by the water pump.

Description

technical field [0001] The invention relates to a fuel cell system. Background technique [0002] Conventionally, there has been proposed a power supply system in which power generation is performed by a fuel cell installed in a vehicle, and power is supplied to home appliances, that is, a power supply system that performs so-called external power feeding. For example, Japanese Patent Laid-Open No. 2014-060068 (hereinafter referred to as "Patent Document 1") proposes a method of detecting a dry state of a fuel cell during external power feeding, and driving a radiator fan to avoid the so-called dry state technology. [0003] Incidentally, considering that when external power feeding is performed by the fuel cell installed in the vehicle, the vehicle is parked, so running wind cannot be introduced into the radiator, and the fuel cell cannot be properly cooled. The power supply system disclosed in Patent Document 1 sends wind to the radiator by driving a fan, and thus cools ...
