An electric car which can easily supply hydrogen to a fuel cell and mounts a hydrogen producing device capable of producing a hydrogen-containing gas at low temperature. The electric car comprises at least a fuel cell (30) for supplying hydrogen and an oxidizer to generate power, a hydrogen producing device (10) for producing a hydrogen-containing gas for supplying to the fuel cell, and a motor driven by electricity produced in the fuel cell, characterized in that the hydrogen producing device, which decomposes an organic-matter-containing fuel to produce a hydrogen-containing gas, comprises a diaphragm (11), a fuel pole (12) provided on one surface of the diaphragm, a means (16) of supplying to the fuel pole a fuel containing organic matters and water, an oxidizing pole (14) provided on the other surface of the diaphragm, a means (17) of supplying an oxidizer to the oxidizing pole, and a means of producing and retrieving a hydrogen-containing gas from a fuel pole side. |
