Abstract: According to one embodiment, a fuel cell includes an electric-power generator, a fuel distribution mechanism, and a pump. The electric-power generator includes a membrane electrode assembly including an anode, a cathode, and an electrolytic membrane. The fuel distribution mechanism includes a container and a thin tube. The container includes a fuel discharge surface, and contains the electric-power generator inside. The thin tube is formed in the container in a manner that a fuel outlet and a fuel inlet communicate with each other. The pump is connected directly to the fuel inlet.

Abstract: A gas-liquid separation system includes a housing at which a gas inlet and a gas outlet are provided; a separation pipe contained in the housing; a separation membrane provided in the separation pipe; and a pump configured to inject a gas into the housing through the gas inlet from an outside of the housing to the gas outlet.

Abstract: The present invention relates to a fuel cell including a plurality of unit membrane electrode assemblies having an electrolyte membrane sandwiched by fuel electrodes and air electrodes. In recent years, attempts have been made to use fuel cells as power sources of portable electronic devices, and if the fuel cell can be made compact, it becomes a remarkably advantageous power supply system for portable electronic devices. Generally, in the fuel cell, the plural unit membrane electrode assemblies are electrically connected in series, but the serial connection of the unit membrane electrode assemblies different in output has a problem such as the deterioration due to polarity reversal occurring in the unit membrane electrode assembly with a low output.

Abstract: A gas-liquid separation system includes a gas-liquid separator configured to separate a gas-liquid mixed fluid into a gas and a liquid; a fuel tank connected to the gas-liquid separator; a bag disposed in the fuel tank; a pressurization pump configured to apply a pressure into the bag; and a pressure control unit configured to control an inner pressure of the gas-liquid separator by controlling a discharge pressure of the pressurization pump.

Abstract: According to one embodiment, a fuel cell apparatus includes a power generator portion which has an anode and a cathode and generates electricity, a fuel tank containing fuel, and a circulating system which supplies fuel and air to the power generator portion. The circulating system includes a fuel passage which allows fuel to circulate through the anode, a gas passage which allows air to circulate through the cathode, and a gas-liquid separator which is provided in the fuel passage between an outflow end of the power generator portion and the fuel tank and separates the fluid into liquid and gas. The gas-liquid separator is connected to the power generator portion so that a flow rate of the fluid that flows from the outflow end of the power generator portion to an inflow end of the gas-liquid separator is 40% or less of a tank capacity of the fuel tank.

Abstract: According to one embodiment, a fuel cell unit is provided with a housing, a electromotive section contained in the housing and including an anode and a cathode, a cooling section which cools a fluid having passed through the cathode and separates the fluid into a gas and a liquid, an exhaust pipe which guides, to an outside of the housing, the gas separated by the cooling section, and a heat transfer mechanism which transfers, to the exhaust pipe, part of heat generated by the electromotive section.

Abstract: A fuel cell device includes: a device body; a fuel cell that is housed in the device body; a user accessible compartment that is disposed in the device body and covered by a detachable cover; an auxiliary unit that is disposed in the user accessible compartment; an air intake port that is disposed in the user accessible compartment draws in air to be used in electricity generation by the fuel cell; and a detachable air intake filter that covers the air intake port.
