摘要： A fuel cell that includes a flow field plate having flow channels, where the flow channels include one enlarged stability flow channel for each set of a predetermined number of smaller flow channels. The stability channel provides a higher volume of flow therethrough, which prevents the accumulation of water at low loads.

A device is configured to convert a hydrogenous fuel source to electrical energy and comprises an electrochemical conversion assembly, first and second reactant inputs, first and second product outputs, and first and second diffusion media. The device is configured such that a mesoporous layer is carried along at least a portion of a major face of one of the first and second diffusion media substrates. The mesoporous layer comprises a hydrophilic carbonaceous component and a hydrophobic component. The mesoporous layer occupies a substantially greater portion of one of the high or low H2O regions of the device, relative to the other of the high or low H2O region of the device.

摘要： A fuel cell plate having a first plate having an inlet aperture and a second plate disposed against the first forming a conduit. The conduit has a continuous seam formed between the first plate and the second plate to facilitate a transport of water to the outlet aperture. The plates can include various indentations and protuberances that form portions of the conduit. The fuel cell plate is well suited for use in a vehicle fuel cell stack for reducing water retention in a fuel cell without increasing the number of required components and fabrication cost of the fuel cell plate.

摘要： A method for optimizing a fuel cell diffusion media having a spatially varying mass transport resistance is provided. The method includes at least two passes where a first-pass D/Deff profile for the fuel cell diffusion media is provided and applied to a computational model of the fuel cell having a baseline variable profile. At least one first-pass variable profile resulting from the application of the first-pass D/Deff profile to the computational mode is calculated and compared to a desired variable range. The first-pass D/Deff profile is refined, if necessary, to provide a second-pass D/Deff profile. A relative performance of the fuel cell with a second-pass variable profile resulting from an application of the second-pass D/Deff profile is determined. The second-pass D/Deff profile is refined, if necessary, until the second-pass variable profile has a desirable performance. An effective D/Deff profile is thereby provided.
