    • A polymer electrolyte fuel cell comprises a fuel cell stack and a humidifier. The fuel cell stack includes plural cells in which each cell has a pair of electrodes and a proton-conductive electrolyte membrane arranged between the pair of electrodes, wherein an oxidant gas or a fuel gas passes through the humidifier before being fed to the fuel cell stack, and wherein a wet gas containing water or water vapor also passes through the humidifier. In the fuel cell, the humidifier includes a porous separating layer and a hydrophilic water-releasing layer, wherein the separating layer is configured to separate the wet gas from the oxidant gas or the fuel gas in the humidifier, and wherein the hydrophilic water-releasing layer is disposed in a side of the oxidant gas or the fuel gas to the separating layer in the humidifier.

    • In an accounting system, an user 1, by the use of a terminal 2, transmits a transmission packet P1 to a reception destination 3, that is a server of an information service provider, and receives a reception packet P2 therefrom by way of a packet communication network 4. The accounting apparatus 6 receives numbers of transmitted and received packets 51 from an exchange 5 and also receives the accounting amendment information 71 from the accounting amendment apparatus 7 at an adequate timing. The accounting apparatus 6 thereby decides the account fees for the user 1 of the terminal 2 and for the reception destination 3, respectively. In other words, the information service provider is charged with a part of the numbers of transmitted and received packets 51.
