Fuel cell system


A fuel cell system according to the present invention comprises: a fuel cell including a membrane-electrode assembly in which electrodes, each having a catalyst layer, are arranged on both surfaces of a polymer electrolyte membrane; a power storage apparatus connected to a load in parallel with the fuel cell; and a control apparatus that performs performance recovery processing for the catalyst layer by decreasing an output voltage of the fuel cell to a predetermined voltage, wherein an intermittent operation in which a power generation command value for the fuel cell is set to zero and a power supply to the load is covered by power supplied from the power storage apparatus is allowed to be performed if certain conditions for performing the intermittent operation are met, and the performance recovery processing is performed during the intermittent operation, and wherein, if the performance recovery processing is necessary and if a remaining power in the power storage apparatus is equal to or lower than a predetermined amount, the control apparatus delays a timing of performing the intermittent operation and charges the power storage apparatus until the remaining power exceeds the predetermined amount.. .

Integrated gaseous fuel cpox reformer and fuel cell systems, and methods of producing electricity


Integrated gaseous fuel catalytic partial oxidation (cpox) reformer and fuel cell systems can include a plurality or an array of spaced-apart cpox reactor units, each reactor unit including an elongate tube having a gas-permeable wall with internal and external surfaces, the wall enclosing an open gaseous flow passageway with at least a portion of the wall having cpox catalyst disposed therein and/or comprising its structure. The catalyst-containing wall structure and open gaseous flow passageway enclosed thereby define a gaseous phase cpox reaction zone, the catalyst-containing wall section being gas-permeable to allow gaseous cpox reaction mixture to diffuse therein and hydrogen rich product reformate to diffuse therefrom.

Bipolar plate for a fuel cell and manufacturing the same


The present invention relates to a separator plate for a fuel cell and to a method for producing the same, and relates to an invention wherein a surface-modification layer is formed through the use of low temperature plasma processing such that it is possible to prevent the hydrophobic characteristics which occur during gasket forming and to have outstanding hydrophilic characteristics, and such that it is possible to obtain the advantageous effect of highly outstanding corrosion resistance and electrical conductivity not only initially but also even after long-term use in a fuel-cell operating environment, and also such that it is possible to maintain outstanding durability even when using a normal low-price stainless-steel sheet base material, and it is possible to reduce the unit cost of production of the separator plate for the fuel cell since surface processing can be carried out at low cost.. .

Fuel supply for a fuel cell


The present invention discloses a fuel supply for a fuel cell, the fuel cell including a liquid storage area that includes a liquid reactant, a reaction area that includes a solid reactant, wherein the liquid reactant is pumped into the reaction area such that the liquid reactant reacts with the solid reactant to produce reaction components, a product collection area that receives the reaction components, a barrier, and a container with an interior volume that substantially encloses the reaction area, liquid storage area, product collection area. The barrier separates and defines several of the aforementioned areas, and moves to simultaneously increase the product collector area and decrease the liquid storage area as the liquid reactant is pumped from the liquid storage area and the reaction components are transferred into the product collection area..
