An alkaline fuel cell electrode catalyst includes a first catalyst particle that contains at least one of iron (Fe), cobalt (Co) and nickel (Ni), a second catalyst particle that contains at least one of platinum (Pt) and ruthenium (Ru), and a carrier for supporting the first catalyst particle and the second catalyst particle.

Alkaline fuel cell electrode catalyst, alkaline fuel cell, manufacture method for alkaline fuel cell electrode catalyst, and manufacture method for alkaline fuel cell

An alkaline fuel cell having an electrolyte, and anode and cathode electrodes disposed on two sides of the electrolyte is provided. A fuel cell system has this fuel cell, a discharge passageway that is connected to a discharge opening of the fuel cell and that discharges from the fuel cell an exhaust fuel containing unreacted fuel, and a circulation passageway that is connected to an introduction opening for introducing the fuel into the fuel cell and that circulates and supplies the exhaust fuel to the fuel cell. The fuel cell system further includes fuel/water separation means linked to the discharge passageway and the circulation passageway and disposed between the discharge and circulation passageways. The means separates and removes water from the exhaust fuel flowing in from the discharge passageway, and then causes a concentrated fuel from which water has been separated and removed to flow into the circulation passageway.

Fuel cell system and operation method therefor

In a fuel cell that includes an electrolyte (), and an anode () and a cathode () which constitute a pair of electrodes that are arranged sandwiching the electrolyte (), the cathode () includes catalyst particles () and trapping particles (). The catalyst particles () operate as catalysts for a reaction that creates hydroxide ions from oxygen, and the trapping particles () trap hydrogen peroxide ions.

Fuel cell

A fuel cell that uses alcohol as a fuel and including an electrolyte, and an anode and a cathode that are disposed across the electrolyte. The anode of the fuel cell contains a first particle that catalyzes the degradation of alcohol, and a second particle that catalyzes the degradation of aldehyde.
