Abstract: An ion-exchange apparatus includes a raw-water tank 1, a treatment section, an ion exchanger and a hydrophilic layer. The raw-water section contains a liquid to be treated with impurity ions. The treatment tank 2 contains a treatment material with exchange ions exchangeable with the impurity ions. The ion exchanger 3 enables the passage of the impurity ions from the raw-water tank 1 to the treatment tank 2 and the passage of the exchange ions from the treatment tank 2 to the raw-water tank 1. The hydrophilic layer M, with a water contact angle of 30° or less, is disposed on at least a surface of the ion exchanger adjacent to the treatment tank 2.

Abstract: A fuel cell system has a cell (1) that is capable of generating electric power. The cell (1) has a fuel electrode (1a), an air electrode (1b) and an electrolyte (1c). The fuel electrode (1a) is supplied with hydrogen obtained by reforming fuel gas. The air electrode (1b) is supplied with oxygen in the air. The electrolyte (1c) is interposed between the fuel electrode (1a) and the air electrode (1b) to enable oxygen ions to pass through to the fuel electrode (1a). A water vapor retaining mechanism (6) is disposed in a flow path of the fuel gas supplied to the fuel electrode (1a). The mechanism (6) retains water vapor generated in the fuel electrode (1a) during electric power generation by the cell (1). The mechanism (6) enables the water vapor to be mixed with the fuel gas.

Abstract: An ion-exchange apparatus has a raw-water tank 1, a treatment tank 2, an ion exchanger 3 and a voltage applying device E. The raw-water tank 1 contains a to be treated liquid that has impurity ions. The treatment tank 2 contains a treatment material with exchange ions exchangeable with the impurity ions. The ion exchanger 3 enables the passage of the impurity ions from the raw-water tank 1 to the treatment tank 2 and the passage of the exchange ions from the treatment tank 2 to the raw-water tank 1. The voltage-applying device E applies a voltage to the ion exchanger 3.
