WATER TANK AND FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a water tank capable of obtaining water for humidification in a short time by quickly melting frozen ice, and a fuel cell system with a short start-up time.

SOLUTION: The water tank 1 is cone-shaped with its tip facing downward. A heat medium tube 4 as a heating means is fitted around and in contact with a cone-shaped tank wall 2. A heat medium 5 heated by combustion heat of hydrogen combustor is circulated in the heat medium tube 4 to melt ice in the water tank 1. A liquid water exhaust tube 3 is communicated with the tip part of the cone of the tank wall 2 and serves as an exhaust outlet for water.
