摘要： A fuel cell may include a first fuel cell bipolar plate defining an air layer, a second fuel cell bipolar plate defining a hydrogen layer, and a coolant layer defined by the air layer and the hydrogen layer. A permeable support infill structure, composed of sintered thermally conductive powder particles, is arranged at the cooling layer to prevent flow blockage at the coolant layer, define a thermally conductive path between the air layer and the hydrogen layer, and facilitate coolant flow through the permeable support infill structure.

摘要： Preform and manufacturing process producing heterogeneous components with a first fraction (11) made from a first metallic material and having a cellular structure with stochastic or regular cells, and a second fraction (12) made from a second metallic material different from the first metallic material, in which the second fraction (12) at least partly infiltrates the cells of the first fraction (11). The second fraction is poured into the preform which also acts as a mould. The finished product after machining may have a unified surface of the second fraction or several zones exposing the second fraction, the first fraction, the cellular structure which is open or infiltrated with the second metallic fraction, or open zones, in a predetermined design.

摘要： A first pre-sintered body composed of a powder made of a first Ni-based alloy is prepared, and a second pre-sintered body composed of a powder made of a second Ni-based alloy is prepared. Subsequently, the first and second pre-sintered bodies are positioned to face each other across a predetermined gap, and a joining material made of a Ni-based alloy having a lower liquidus temperature than the first and second Ni-based alloys is placed in a space that adjoins the first and second pre-sintered bodies and to which the gap opens. After the placing of the joining material, the first and second pre-sintered bodies are heated to melt the joining material, fill the gap with the molten joining material, and subsequently turn the first and second pre-sintered bodies into first and second sintered bodies, respectively.

摘要： An apparatus for dispensing build powder and support powder, in a sequence of layers, and having a frame and a container. Also, a build powder pourer is at least partially filled with build powder and a support powder pourer at least partially filled with support powder, each of the pourers having a dispensing opening and a dispensing plug, controllably covering the dispensing opening. Further, a pourer-movement and dispensing plug-actuating assembly is supported by the frame over the container and includes a movement element that is selectively attachable to the build powder pourer and alternately to the support powder pourer and also capable to controllably move an attached pourer in three orthogonal dimensions and to control the dispensing plug. In addition, at least one docking station for holding a first one of the pourers; and a computing assembly controls the pourer-movement and dispensing plug-actuating assembly to create a target shape.

摘要： The invention is a process for manufacturing a nano aluminum/alumina metal matrix composite and composition produced therefrom. The process is characterized by providing an aluminum powder having a natural oxide formation layer and an aluminum oxide content between about 0.1 and about 4.5 wt. % and a specific surface area of from about 0.3 and about 5 m2/g, hot working the aluminum powder, and forming a superfine grained matrix aluminum alloy. Simultaneously there is formed in situ a substantially uniform distribution of nano particles of alumina. The alloy has a substantially linear property/temperature profile, such that physical properties such as strength are substantially maintained even at temperatures of 250° C. and above.
