Abstract
A fuel cell device comprising a fuel cell cartridge having a container for containing methanol mixed solution fuel and a direct methanol fuel cell on which the fuel cartridge is set the fuel cartridge being provided with a fuel injection nozzle on part of the container and a projection disposed around the fuel injection nozzle; the size of which is determined according to the concentration of methanol of the fuel in the container, and the direct methanol fuel cell being provided with a concavity, which is designed to engage with the projection of the fuel cartridge at a portion where the fuel cartridge is to be set when the concentration of methanol is proper.
Claims11
A fuel cell device comprising a fuel cell cartridge having a container for containing methanol mixed solution fuel and a direct methanol fuel cell on which the fuel cartridge is set;
- the fuel cell cartridge being provided with a fuel injection nozzle on part of the container and a projection disposed around the fuel injection nozzle;
- the size of which is determined according to the concentration of methanol of the fuel in the container, and the direct methanol fuel cell being provided with a concavity, which is designed to engage with the projection of the fuel cartridge at a portion where the fuel cartridge is to be set, when the concentration of methanol is proper.
A fuel cartridge for use in a fuel cell, which is provided with a container for containing a methanol mixed solution fuel, a fuel injection nozzle on the container and a projection disposed around the nozzle, the size of which is determined according to the concentration of methanol of the fuel in the container.
A direct methanol fuel cell for use in a fuel cell device, which is provided with a concavity designed to engage with a projection provided on a container containing a methanol mixed solution fuel of the fuel cartridge when the concentration of methanol of the fuel is proper.
A fuel cell device comprising a fuel cell cartridge having a container containing a methanol mixed solution fuel, a fuel injection nozzle on part of the container, and a projection disposed around the nozzle, the size of which is determined according to the concentration of methanol of the fuel in the container, and an electric contact on the surface the fuel injection nozzle of the container is provided;
- and
- a direct methanol fuel cell provided with a concavity, which is designed to be able to engage with the projection when the concentration of methanol is proper, at a portion the fuel cartridge is to be set and an electric contact to get in touch with the electric contact of the fuel cartridge;
- wherein
- the fuel is supplied from the fuel cartridge to the fuel cell when the projection of the fuel cartridge is engaged with the concavity and also the two electric contacts get in touch with each other and become electrically connected.
