Abstract
Disclosed is a fuel for fuel cells which contains at least one organic compound selected from the group consisting of methanol, ethanol, dimethyl ether and formic acid, and 1-200 ppm of a hydrocarbon compound in terms of a single component as determined by gas chromatography mass spectrometry. Also disclosed are a fuel cartridge for fuel cells and a fuel cell.
Claims20
A fuel for fuel cell, comprising:
- at least one type of organic compound selected from the group consisting of methanol, ethanol, dimethylether and formic acid;
- and
- a hydrocarbon-based compound in amount of 1 to 200 ppm in terms of a single component measured by a gas chromatography mass spectrometry.
A fuel cartridge for a fuel cell, comprising:
- a fuel container and a fuel contained in the container, the fuel contains:
- at least one type of organic compound selected from the group consisting of methanol, ethanol, dimethylether and formic acid, and
- a hydrocarbon-based compound in amount of 1 to 200 ppm in terms of a single component measured by a gas chromatography mass spectrometry.
A fuel cell comprising:
- a fuel storage portion which stores a fuel containing at least one type of organic compound selected from the group consisting of methanol, ethanol, dimethylether and formic acid;
- a fuel gasifying portion that allows a gasified component of the fuel to pass through;
- and
- a membrane electrode assembly including a fuel electrode to which the gasified component is supplied, an oxidizer electrode and a polymer electrolyte membrane provided between the fuel electrode and the oxidizer electrode,
- wherein an amount of a hydrocarbon-based compound contained in the fuel held in the fuel storage portion, the fuel gasifying portion and the membrane electrode assembly is 1 to 1500 ppm in terms of a single component measured by a gas chromatography mass spectrometry.
