Abstract: There is provided a process for sealing a coolant plate to an adjacent bi-polar plate or coolant plate in an electrochemical cell. The first coolant plate comprises at least one mating region for mating with a complementary region on the adjacent plate, the adjacent plate is a second coolant plate or a bipolar plate of the electrochemical cell, and the first coolant plate and the adjacent plate each comprise a polymer and conductive filler. The process comprises the step of welding the mating region to the complementary region to create a seal formed by the polymer at the mating region and the complementary region. Welding may be done using resistance welding or vibration welding processes.

Abstract: An invention is disclosed relating to an apparatus and method for hosting transactions over a network such as the Internet. Sellers post offers to sell under a listing belonging to an organized database of listings. Likewise, buyers post offers to buy. A matching module selects offers to sell and matches them to offers to buy based on a predefined criteria. Before posting offers to sell or buy, buyers and sellers may be presented with data concerning the market for the product that is the subject of the offer. A sale is consummated between the buyer and seller of the matched offer to buy and offer to sell. Consummation may include assessing the risk of fraud posed by the matched buyer and matched seller. Fees may be charged to the matched buyer, the matched seller, or both as insurance against fraud. Payment may be made by the buyer directly to the seller or to a host hosting the apparatus and method for conducting the transaction.
Abstract: The invention is directed to an electrode, suitable for use in a fuel cell, consisting of a microporous current collector incorporating a multitude of domains and wherein each domain contains soluble redox catalyst.

Abstract: Disclosed is a reusable locking unit and a one time use electrically conductive molded thermoplastic shackle loaded with carbon black particles and having a linear resistance that is periodically monitored. The locking unit includes an integrated circuit for measuring shackle impedance through terminals capacitively coupled to the shackle. The terminals allow for adjustment of the length of the seal shackle in the locked secured state. The terminals and shackle form an RC network having a complex impedance that manifests the locked adjusted shackle length. Two AC signals at two different frequencies are used to measure impedance, which is compared with an initially determined or continually generated reference impedance to determine a tampered state of the shackle. Temperature compensation is also disclosed. A time stamp is stored for noting the tampering time of occurrence.
