設備を設けることが規定されている。2. Description of the Related Art It is known that storage batteries generate hydrogen gas when charged. For this reason, the Fire Prevention Ordinance of the Fire Service Act; Fire Prevention Ordinance established in each municipality based on Self Extinguishing Service No. 73; for example, in the case of Tokyo, Tokyo Fire Prevention Ordinance, Tokyo Ordinance No. 65. No., etc. are defined. The gist of this content is "It is dangerous for 3.8% or more of hydrogen gas to accumulate in the storage battery room, so it is necessary to provide an appropriate ventilation port or ventilation fan." Also, "In the room where the storage battery equipment is installed, Is to provide effective ventilation equipment that effectively communicates outdoors. ” That is, it is stipulated that the storage battery equipment should be provided with ventilation equipment because hydrogen gas may be generated.

いられる。Corresponding to these regulations, according to the Japan Battery Association Technical Data "Technical Data on Battery Room" SBA6503, "Hydrogen gas concentration (capacity ratio) is kept at 3% or less" for natural ventilation vents. The relationship between the minimum exhaust area and the current value consumed to generate hydrogen gas is shown. According to JECA 1032, “Guidelines for Power Supply and Wiring of Disaster Prevention Equipment” of the Japan Electric Construction Industry Association, for ventilation fans for forced ventilation, the calculation formula of ventilation equipment capacity is described in the section “Ventilation equipment”. However, in order to realize these ventilation facilities, generally, large-scale construction is required for buildings and the like.

いるのが実情である。On the other hand, in the technical development of the storage battery itself, in recent years, there have been storage batteries such as a catalyst plug type seal type storage battery and a cathode absorption type seal type storage battery, which are said not to generate hydrogen gas in a normal use environment. But the reality is
For example, even when using a cathode absorption seal type storage battery or the like, it is the actual situation that ventilation equipment is provided for reasons such as safety.

る構造を採用している。The catalyst-plug type storage battery is a storage battery having a structure in which oxygen gas and hydrogen gas generated from the storage battery are brought into contact with the catalyst, recombined to generate water, and then returned to the storage battery. However, even in the case of this catalyst plug type storage battery, when a large amount of gas is generated due to overcharge or the like, the oxygen gas and hydrogen gas generated due to the abnormal rating are released to the outside of the storage battery.

The discharge state is set to suppress the hydrogen gas generated from the cathode plate. Therefore, hydrogen gas is not generated from the cathode plate in the range where the generation rate of hydrogen gas generated from the cathode plate and the gas absorption rate at the cathode are in equilibrium.
