Abstract: An inexpensive ion-exchange apparatus with an increased ion-exchange capacity has a raw-water tank (1), a treatment tank (2) and an ion exchanger (3). The raw-water tank (1) contains a to be treated liquid. The liquid contains impurity ions. The treatment tank (2) contains a treatment material that contains exchange ions exchangeable with the impurity ions. The ion exchanger (3) enables 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 treatment material in the treatment tank (2) has a higher molarity than the to be treated liquid in the raw-water tank 1.

Abstract: A fuel cell system has a cell 1, generating power, with a fuel electrode 1a, an air electrode 1b, and an electrolyte 1c. A water vapor retention member 11 is disposed on a communication path for the fuel gas supplied to the fuel electrode 1a. The retention member 11 retains water vapor, generated by the fuel electrode 1a along with power generation by using the cell 1 and mixes the water vapor with the fuel gas. The retention member 11 has a reforming catalyst that enables the hydrogen, generated by reacting the fuel gas, to be supplied. Exhaust ports 13a exhaust fuel gas toward positions on a surface of the water vapor retention member 11.
