Abstract: 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.

Abstract: Systems and methods are provided for simulating rev-matching in hybrid electric vehicles (HEVs). In particular, increased engine response is provided while downshifting during acceleration. The transmission of an HEV may include an electronic control unit that controls the speed of the engine to simulate gears, and increases the speed of the engine responsive to a driver using the gear selector to shift from one of the simulated gears to a lower one of the simulated gears, thereby providing the desired rev-matching experience. The increased engine response can be reflected in a target engine speed that is calculated based on specific gear ratios associated with each of the simulated gears.
