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.

The present disclosure relates to a pharmaceutical composition for preventing or treating statin-induced adverse effects or a pharmaceutical composition for co-administration with statin, the pharmaceutical composition containing, as an active ingredient, at least one selected from the group consisting of an isoprenoid-based compound, zaragozic acid, terbinafine, and ketoconazole. The pharmaceutical composition according to the present disclosure may prevent and/or treat adverse statin effects that can be induced by statin, that is, can be induced at any time by oxisterols present at abnormal levels in the body. The pharmaceutical composition can not only treat but also prevent the adverse effects of various statin therapeutics whose use has recently increased rapidly, and thus it is expected that the pharmaceutical composition can be widely used for various diseases and the utilization thereof can further be increased.

A fuel cell system includes a fuel cell stack that produces electric power and water through an electro-chemical reaction of hydrogen and air. A controller of the fuel cell system calculates an amount of water in the fuel cell stack based on output power of the fuel cell stack and a maximum amount of residual water to which the amount of water in the fuel cell stack converges over time. The fuel cell system may detect the amount of water in the fuel cell stack in real time.

Fuel cell system and method for controlling the same

A method of controlling the driving of a fuel cell system includes: determining whether the fuel cell system enters idle stop in which air supply to the fuel cell stack stops; dropping a DC-link terminal voltage controlled by a DC-DC converter up to a first set voltage by controlling an operation of the DC-DC converter connected to a DC-link terminal outputting generation power of the fuel cell stack at the time of entering the idle stop; and dropping a voltage of the fuel cell stack to reduce an oxide of platinum which is a catalyst of a fuel cell by allowing the anode exhaust gas to flow backward into a cathode of the fuel cell stack by performing the hydrogen purge in an idle stop state of opening the hydrogen purge valve after the voltage of the DC-link terminal drops.

The present invention provides a method for removing residual water in a fuel cell, which controls the humidity of purge gases to effectively remove residual water in the fuel cell and to maintain the humidity in a membrane at a constant level, thus ensuring the durability of the membrane. For this purpose, the present invention provides a method for removing residual water in a fuel cell, characterized in that the relative humidities of purge gases supplied to an anode and a cathode are controlled to selectively reduce water content in the fuel cell and water content in a membrane.

Method for removing residual water from fuel cell

The present invention provides a fuel cell bipolar plate in which an air gap or a material layer having a heat transfer coefficient lower than that of the bipolar plate is provided so as to reduce total amount of liquid water generated in a fuel cell, thereby preventing the occurrence of flooding and reducing the time required for cold start, enhancing durability, decreasing parasitic purge requirements, and enhancing operational stability.

A separating plate for a fuel cell includes first and second plates, each provided with a hydrogen channel, an oxygen channel, and a coolant channel. The first and second plates are attached to one another to form a main plate such that the first and second hydrogen, oxygen, and coolant channels compose main hydrogen, oxygen, and coolant channels, respectively. The main hydrogen and oxygen channels are fluidly isolated from each other. Distal ends of the main channels each communicate with a manifold through a communication passageway configured to supply hydrogen, oxygen, or coolant to a corresponding one of the main channels.
