    Abstract: The present invention provides a solid oxide fuel cell (SOFC) including a “porous fuel electrode which allows reaction of a fuel gas to proceed and which is formed of Ni and YSZ”; a “porous air electrode which allows reaction of an oxygen-containing gas to proceed”; and a “dense solid electrolyte membrane which is provided between the fuel electrode and the air electrode and which has an interface with the fuel electrode.” In the fuel electrode, Ni grains present in a region located within 3 μm from the interface (i.e., a “near-interface region”) have a mean size of 0.28 to 0.80 μm; YSZ grains present in the “near-interface region” have a mean size of 0.28 to 0.80 μm; and pores present in the “near-interface region” have a mean size of 0.10 to 0.87 μm. Thus, the fuel electrode of the SOFC exhibits low reaction resistance.

    Abstract: A cathode of a solid-oxide fuel cell includes a first ionic conducting layer, a second layer deposited over the first layer and formed from a mixed ionic and electronic conductor layer including an oxygen ion conducting phase, and a third layer deposited over the second layer and formed from a mixed ionic and electronic conductor layer. A sintering aid and pore formers are added to the second layer and the third layer to establish ionic, electronic, and gas diffusion paths that are contiguous. By adjusting the microstructure of the second and the third layer, a high performance low resistance cathode is formed that bonds well to the electrolyte, is highly electro-catalytic, and has a relatively low overall resistance. By using inexpensive and readily available substances as sintering aid and as pore formers, a low-cost cathode is provided.

    Abstract: A current collector and method of forming the same in which a slurry is prepared that contains electrically conductive particles having surface deposits of a metallic oxide on a metal or metal alloy conductor that has a lower weight percentage of the electrically conductive particles than the metal or metal alloy. The slurry is applied to a structure that contains an electrolyte and electrode layers. The resultant coated form is then fired to partly sinter the electrically conductive particles and thereby to obtain porous current collector layers affixed to the electrode layers. The current collector of the present invention is between about 5 microns and about 100 microns thick and preferably has a porosity of between about 10 percent and about 70 percent with pores having a pore size of between about 0.1 microns and about 20 microns.

    Abstract: A method of forming a membrane electrode assembly (MEA) includes first bonding a first electrode layer to a first side of an ion-exchange membrane. The method may further include protecting a second side of the membrane with a release sheet. The method may further include removing the release sheet and bonding the second side of the membrane to a first side of a second electrode layer. The method may further include positioning venting members on a second side of the second electrode layer to remove at least one of a liquid and a vapor that may be generated during the bonding process. In another embodiment an electrocatalyst can first bond to at least one side of the membrane, and subsequently, to a gas diffusion layer. An opposing side of the membrane can bond to an electrode layer in aqueous state.
