Abstract

A communication terminal, to which a power is supplied from the fuel cell, includes an ID detecting unit that detects at least one of unique identification information of a fuel reservoir for supplying fuel to the fuel cell and unique identification information of the fuel cell, a content detecting unit that detects a content executed in the communication terminal, a cell driving detecting unit that detects an operating state of the fuel cell, and a matching process unit that collates and associates with each other data obtained from the ID detecting unit the content detecting unit and the cell driving detecting unit.

Claims

1. A communication terminal, to which a power is supplied from a fuel cell, comprising:

an execution/reproduction unit that executes or reproduces a service content that is provided or supplied from a service content provider;

an ID detecting unit that detects a fuel cell identification data indicating at least one of unique identification information of a fuel reservoir for supplying fuel to the fuel cell and unique identification information of the fuel cell;

a content information detecting unit that detects information of the service content that is executed or reproduced by the execution/reproduction unit;

a cell operating state detecting unit that detects an operating state of the fuel cell; and

a matching process unit that collates and associates the fuel cell identification data, the information of the service content, and the operating state of the fuel cell.

2. The communication terminal according to claim 1,

wherein the matching process unit calculates an amount of fuel consumed by executing one content in the communication terminal.

3. The communication terminal according to claim 1,

wherein the data collated and associated by the matching process unit is encrypted, and

a encrypted data is transmitted to a communication management system to which the communication terminal is connected.

4. The communication terminal according to claim 1,

wherein the content information detecting unit has a function that obtains metadata of the content.
