Abstract

An in-vehicle hydrogen storage apparatus has a hydrogen gas filling passage connected from a hydrogen gas filling port up to the storage device that stores a hydrogen gas to be supplied to a fuel cell, and an odorizing agent supplying device that supplies an odorizing agent to hydrogen gas in at least one of the inside of the storage device and the inside of the hydrogen gas filling passage.

Claims (13)

1. A hydrogen supply system, comprising:

a storage device that stores hydrogen gas supplied to a fuel cell;

a hydrogen gas filling passage that connects a filling port of the hydrogen gas filling passage to the storage device; and

an odorizing agent supplying device that supplies an odorizing agent to the hydrogen gas in at least one of the inside of the storage device and the inside of the hydrogen gas filling passage;

a controller programmed to control the odorizing agent supplying device to supply odorizing agent in an amount corresponding to the flow amount of hydrogen gas; and

a hydrogen filling station that supplies hydrogen gas to the storage device, wherein the hydrogen filling station includes:

an acquisition device that acquires a flow amount of the hydrogen gas to be supplied into the storage device; and

a communication device that sends the acquired flow amount of hydrogen gas to the controller,

wherein the hydrogen filling station includes a plurality of hydrogen tanks that contain hydrogen gas mixed with different odorizing agents, and

the controller programmed to communicate data identifying a prescribed odorizing agent to the communication device, and is programmed to perform a control so that the storage device is supplied with hydrogen gas that includes the prescribed odorizing agent.

2. The hydrogen supplying system according to claim 1 , wherein the communication device stores data identifying additives of the hydrogen gas provided by the hydrogen filling station, and wherein the controller acquires the data by communication and controls the amount of odorizing agent added to the hydrogen gas based on the acquired data.

3. The hydrogen supplying system according to claim 1 , wherein the controller executes a control so that odorizing agent is not added to the hydrogen gas when an amount of odorizing agent contained in the hydrogen gas supplied to the storage device is greater than a prescribed value, the acquired data indicating the amount of odorizing agent.

4. The hydrogen supplying system according to claim 1 , wherein the odorizing agent supplying device includes a normally-closed electromagnetic valve that, when electrically powered, opens to supply odorizing agent to at least one of the inside of the storage device and the inside of the hydrogen gas filling passage.
