PURPOSE:To stabilize exhaust heat recovery from cell cooling water in a fuel cell at the constant temperature or pressure of the cell cooling water. CONSTITUTION:A partition plate 30 having an upper opening is housed inside a deaerator 5 used for a cell cooling water circulating circuit for a fuel cell, thus defining a water supplying space 31 independently of a cell cooling water circulating space 32. Water supplied to the deaerator 5 is temporarily stored in the water supplying space 31, followed by heating by high temperature cell cooling water stored in the cell cooling water circulating space 32, to be supplied into the cell cooling water circulating space 32 through the upper opening of the partition plate 30. Consequently, it is possible to restrain a temperature or pressure of the cell cooling water from being varied due to low temperature supply water so as to stabilize exhaust heat recovery from the cell cooling water. |
