Description

  The present invention relates to a portable fuel cell device, and more particularly, a portable fuel cell device that can be freely transported even in a narrow passage and can be used as a power source for construction sites, an emergency power source during a disaster, and a power source for leisure. About.

Conventionally, lead batteries have been used as uninterruptible power supplies and emergency power supplies. This lead battery has a lifetime and must be replaced periodically. In addition, the lead battery has a problem that the processing load after disposal is large. Therefore, in recent years, a fuel cell has attracted attention as a power supply device that has less burden on the environment and is superior in conversion efficiency compared to a lead battery. In particular, a fuel cell using hydrogen as a fuel is expected to be widely used as an environmentally friendly power supply device because water is discharged. In recent years, fuel cells with excellent fuel-to-electricity conversion efficiency have been developed with small size and high output, and the equipment itself can be moved. It can be used as a power source and a leisure power source. Conventionally, “portable fuel cell devices” described in Patent Documents 1 to 4 have already been proposed as fuel cell devices that enable movement of the device.
