A mobile waterborne energy platform systems and methods comprising a purpose built marine vessel, a pre fabricated building structure, a plurality of fuel cells or generators, a plurality of fuel tanks, a plurality of mechanical equipment, a plurality of electrical equipment and a method to transmit electrical power to shore or to another marine vessel. The mobile waterborne energy platform systems and methods described may be employed to quickly provide utility grade electrical power to remote austere locations. The electrical power may be produced by a plurality of fuel cells or generators configured on a mobile waterborne vessel that may be transported to remote areas to provide an on site electrical power source for critical infrastructure, communications, emergency or medical facilities. The systems and methods are ideal for military purposes where troops may be deployed in remote locations without readily available utility grade electrical power.

An ion exchanger includes a case that is provided with an opening, an intake port, and a discharge port. The opening opens upward in the case. Coolant is drawn into the lower portion of the case through the intake port and discharged through the discharge port. An ion exchanging resin member and a cap are provided in the case. The ion exchanging resin member removes ions from the coolant. The cap is detachably attached to the case and closes the opening of the case. The ion exchanger further includes a tube member that is arranged to extend vertically in the case. The lower end aperture of the tube member is connected to the discharge port of the case. The upper end aperture of the tube member faces the inner top surface of the lid portion of the cap.

A fuel cell stack includes a coolant channel provided between a first separator of a first power generation cell among power generation cells and a second separator of a second power generation cell among the power generation cells which is adjacent to the first power generation cell. A coolant manifold is connected to the coolant channel. A coolant manifold end member is connected to the coolant manifold. The coolant manifold end member includes an air vent wall having an opening provided at an uppermost position of the coolant manifold end member in a height direction of the fuel cell stack. The coolant manifold end member includes a wall which surrounds the air vent wall and which is thinner than the air vent wall. The air vent pipe protrudes from the air vent wall. The air vent pipe and the coolant manifold end member are integrally made.

Provided is a fuel cell system including a fuel cell, a radiator that is provided in a circulation path of coolant that cools the fuel cell, a spray unit that sprays, toward the radiator, generated water that has been generated in and discharged from the fuel cell, and a heating unit that is provided in a supply path of the generated water from the fuel cell to the spray unit and heats the generated water.

A fuel cell device comprises a fuel cell stack which is formed from a plurality of unit cells stacked one above the other in a stacking direction, each unit cell having one or more media channels and a membrane electrode assembly that comprises a cathode, an anode, and a membrane arranged between the cathode and the anode, and comprising a media duct running substantially parallel to the stacking direction. The media duct is connected or can be connected to the fuel cell stack to conduct a medium into or out of the media channels of the unit cells of the fuel cell stack substantially laterally to the stacking direction. The media duct is formed as a functional component or such a functional component is integrated therein, which is formed to pre-treat the medium before it enters the media channels or to post-treat the medium after it has exited the media channels.

A fuel cell system includes a fuel cell stack constituted by cells, each of the cells includes a fuel electrode, an air electrode, and an electrolyte, and generate electric power through a reaction of a fuel gas and air, a casing that houses the fuel cell stack, a temperature detector that detects a first temperature, the first temperature is a temperature of the fuel cell stack or inside the casing, and a controller. The controller controls based on the first temperature so as to allow an operation at a first predetermined temperature. The controller controls such that the first temperature reaches a temperature higher than or equal to a second predetermined temperature for a predetermined time. The second predetermined temperature is a temperature at which 475° C. embrittlement that occurs on stainless steel is eliminated. The first predetermined temperature is lower than the second predetermined temperature.
