An apparatus for controlling a moisture content of a fuel cell unit includes: a controller configured to determine a driving condition of a first fuel cell unit comprising a first fuel cell stack, a first compressor configured to compress air flowing into the first fuel cell stack, and a first humidifier positioned on a rear end of the first compressor, determine a driving condition of a second fuel cell unit comprising a second fuel cell stack, a second compressor configured to compress air flowing into the second fuel cell stack, and a second humidifier positioned on a rear end of the second compressor, and control the moisture content such that the first fuel cell unit and the second fuel cell unit are driven at controlled operation temperatures in response to the determined driving conditions of the first fuel cell unit and the second fuel cell unit.

A fuel cell includes a membrane electrode assembly including a membrane, a cathode, and an anode, a first gas diffusion layer stacked on an outer surface of the cathode, a second gas diffusion layer stacked on an outer surface of the anode, a separator stacked on an outer surface of the first gas diffusion layer, and a reaction gas channel provided in the separator, wherein the reaction gas channel includes an inlet region, an outlet region, and a central region provided between the inlet region and the outlet region with respect to a flow direction of a reaction gas flowing through the reaction gas channel, wherein an electric resistance of the separator in the inlet region or the outlet region is greater than an electric resistance of the separator in the central region.

Fuel cell and automobile including the same

Disclosed are an electrode gas diffusion layer assembly (EGA) and a fuel cell stack including the same. The content of the binder in the electrode and the content of the binder in the adhesive layer that attaches the electrode to the gas diffusion layer (GDL) may be optimized. Thus, it is possible to reduce the occurrence of flooding and the deterioration in durability/performance caused by a dry atmosphere in the EGA including the electrode and the adhesive layer, so that the output density per unit area is improved while the trade-off is minimized.

A fuel cell stack includes a power generation cell having a first gas diffusion layer and a dummy cell disposed at an end of the power generation cell and having a second gas diffusion layer with higher thermal conductivity than the first gas diffusion layer. An end plate is fastened at an end of the dummy cell and a heater is interposed between the dummy cell and the end plate.

A method for estimating a hydrogen concentration of a fuel cell includes estimating an initial amount of gas included at an anode side of a fuel cell, calculating a crossed over amount of gas between the anode side and a cathode side of the fuel cell and an amount of gas purged from the anode side to the outside from time when an initial amount of gas is predicted to a present time, and estimating a current hydrogen concentration at the anode side based on the predicted initial amount of gas, the calculated amount of crossed over gas, and the amount of purged gas.

Method and system for estimating hydrogen concentration of fuel cell

A system and method for controlling dehydration of a fuel cell stack include a fuel cell stack including an anode which receives hydrogen from a hydrogen supplier and a cathode which receives air from an air supplier. A reactor collects hydrogen and oxygen discharged from the fuel cell stack so that the collected hydrogen and oxygen are reacted, thereby increasing relative humidity of hydrogen supplied to the anode, and thus raising water content of the catalytic layer of the anode.
