    摘要: An electrochemical cell separator plate formed from a mixture of carbonizable resin and coke particles, wherein the plate is molded from the resin and coke particles, carbonized, and graphitized. The particle size distribution of the coke is selected so that expansion occurring during graphitization minimizes the rupture of carbonized bonds within the separator plate. The separator plates have improved properties over separator- plates formed from graphite particles including increased density, decreased porosity and increased corrosion resistance. The coke particle plates are more energy efficient to manufacture than graphite particle plates.

    摘要: Heat treating of a material containing a carbon degradable content is carried out by segmenting the temperature range of heat treating into at least two intervals, a first one of which is able to support heat treating without blistering of the material at a first maximum rate and a second one of which is able to support heat treating without blistering at a second maximum rate different from the first rate, and the material is heated at a first rate equal to or less than the first maximum rate in the first interval and at a second rate different from the first rate and equal to or less than the second maximum rate in the second interval.

    摘要: A seal structure 60 for a porous plate of an electrochemical cell, such as plates 18, 20, includes a sealing material disposed in a seal region 66 of the plate to form a hydrophilic barrier to gas with an electrolyte and a hydrophobic layer 62 to block the loss of electrolyte from the hydrophilic layer is disclosed. Various construction details including a method of making the plate are disclosed which increase the cross pressure the sealing region of the plate can withstand. In one embodiment, the seal region 66 is impregnated with powder having a low structure and predetermined particle size using a pressurized liquid carrier. A FEP Teflon film bonds adjacent electrolyte reservoir plates together.

    摘要: A fuel cell matrix comprising a first layer of material having opposing first and second surfaces and second and third layers of material each adjacent one of said opposing surfaces, the first and second layers having different dimensional expansion with electrolyte addition, whereby said layers tend to curl, and the third layer having dimensional expansion with electrolyte addition such as to counteract the curling of said first and second layers.
