摘要： A bipolar plate with an enhanced fluid flow field design is provided for a fuel cell. The bipolar plate includes an inlet, an outlet, and a flow field having a pattern defining a plurality of microchannels configured to provide fluid communication between the inlet and the outlet. The pattern is designed using an inverse permeability field, and is based on a reaction-diffusion algorithm to model channel spacing, thereby providing a variable pitch microchannel pattern to direct fluid from the inlet to the outlet. In various aspects, the reaction-diffusion algorithm utilize Gray-Scott reaction-diffusion equations, which may be used to obtain an anisotropic microchannel layout. The variable pitch microchannel pattern may include a channel spacing based on effective medium theory.

摘要： A fuel electrode incorporates a first and second corrugated portion that are attached to each other at offset angles respect to their corrugation axis and therefore reinforce each other. A first corrugated portion may extend orthogonally with respect to a second corrugated portion. The first and second corrugated portions may be formed from metal wire and may therefore have a very high volumetric void fraction and a high surface area to volume ratio (sa/vol). In addition, the strands of the wire may be selected to enable high conductivity to the current collectors while maximizing the sa/vol. In addition, the shape of the corrugation, including the period distance, amplitude and geometry may be selected with respect to the stiffness requirements and electrochemical cell application factors. The first and second corrugated portions may be calendared or crushed to reduce thickness of the fuel electrode.

摘要： A fuel cell seal structure includes stacked fuel cells and an electrolyte membrane or a film supported between the neighboring metal separators. Each of the stacked fuel cells includes neighboring metal separators each including a plate portion having a plate portion surface, a bead seal portion projecting from the plate portion surface and including a distal end having a distal end surface, an elastic body disposed on the distal end surface, and a stopper disposed on the plate portion surface and away from the elastic body. The neighboring metal separators are disposed such that elastic bodies are located opposed to each other in a stacking direction with the electrolyte membrane or the film supported in between the elastic bodies and face each other, and such that stoppers are located neighboring to each other in the stacking direction with the electrolyte membrane or the film supported in between the stoppers.

摘要： A power generation cell of a fuel cell stack includes a resin frame equipped MEA and a first metal separator and a second metal separator. In the power generation cell, the relationship of P1>P2>P3 is satisfied, where P1 indicates a first surface pressure applied from a first seal part and a second seal part to a resin frame member, P2 indicates a second surface pressure applied from a first support part and a second support part to the overlap part, and P3 indicates a third surface pressure applied from first flow field forming protrusions and second flow field forming protrusions to the power generation area.

摘要： An alloy member includes a base member constituted by an alloy material containing chromium, a chromium oxide layer for covering at least a portion of a surface of the base member, a pore that is formed in an interface region of the base member that is located 30 μm or less from an interface between the chromium oxide layer and the base member, and an extending portion extending from the pore into the base member. The pore is configured to inhibit the separation of the chromium oxide layer from the base member The extending portion contains an oxide of an element whose equilibrium oxygen pressure is lower than that of a major element of the base member.
