A fuel cell system includes a controller that controls actions of the fuel cell system. The controller includes a freezing presence-absence determination unit that performs freezing presence-absence determination, a temperature raising execution unit that performs temperature raising processing for raising a temperature of an exhaust and drain valve, and a thawing presence-absence determination unit. In the freezing presence-absence determination, freezing determination is made when the exhaust flow rate of gas is equal to or lower than a first threshold. In the thawing presence-absence determination, thawing determination indicating that the exhaust and drain valve is thawed is made when the exhaust flow rate of gas is higher than a second threshold. The second threshold shows a flow rate higher than the first threshold.

A method for producing an anode capable of increasing output of a solid oxide fuel cell is provided. The method for producing an anode for a solid oxide fuel cell includes a first step of shaping a mixture that contains a perovskite oxide having proton conductivity and a nickel compound and a second step of firing a shaped product, which has been obtained in the first step, in an atmosphere containing 50% by volume or more of oxygen at 1100° C. to 1350° C. so as to generate an anode.

An electrochemical cell has at least one plate element which can be cooled by a liquid coolant, such as water. The plate element has a surface that can be wetted for the purpose of cooling with the coolant. The surface of the plate element in the electrochemical cell is configured such that a contact angle between the surface and the liquid coolant is less than 90°. In the method for producing the electrochemical cell an additional method step is carried out which influences the wettable surfaces of plate elements for cooling with coolant and by which a contact angle between the surface and the coolant is decreased.

A method of producing a flow field plate for a fuel cell comprises over-profiling relief features in a die set to more accurately reproduce the intended flow channel features in the pressed plate. The process includes determining a target relief profile of features extending across the plate along at least a first dimension of the plate, modulating the relief profile with an over-profiling parameter, as a function of the first dimension; forming a die with the modulated relief profile; and pressing a flow field plate using the die with modulated relief profile to thereby produce the unmodulated, target relief profile in the flow field plate.

Discloses is a porous separator for a fuel cell. The porous separator includes a flow plate and a flat plate. The flow plate includes a first flow surface upwardly inclined and having a first plurality of flow apertures and a second flow surface downwardly inclined and having a second plurality of flow apertures that are repeatedly arranged along a longitudinal direction of the flow plate. The flow plate is disposed between a gas diffusion layer of a fuel cell and a flat plate to seal the flow plate and create a flow path for hydrogen or air therein.

A cell including: a body having a first end portion and a second end portion; a first electrode layer electrically connected to the body; a solid electrolyte layer located on the first electrode layer; and a second electrode layer located on the solid electrolyte layer, wherein the body includes a plurality of gas-flow passages passing through the body from the first end portion to the second end portion; and the plurality of gas-flow passages include: one or more center-shifted gas-flow passages that include: a central portion and a first end portion; wherein a center of the one or more center-shifted gas-flow passages at the central portion is laterally shifted from a center of the one or more center- shifted gas-flow passages at the first end portion and a diameter of the one or more center-shifted gas-flow passages gradually increases from the central portion to the first end portion.
