Patent CA-2320210-A1 (CA)
Inventor: DOHLE HENDRIK
IPC: H01M8/241
Filed: 1999-01-14
Abstract: Existing fuel cells with proton conducting electrolyte use a membrane made of perfluorinated plastic material as electrolyte and are powered using hydrogen or methanol as fuel. One disadvantage is that said electrolyte membrane allows both the protons and the fuel to pass through resulting in a loss in fuel cell efficiency.   Migration of the fuel molecules through the electrolyte (14) from the anode side to the cathode side is prevented in such a way that the fuel cell exhibits a hydrogen permeable barrier layer composite (20) comprising two outer layers (22, 24) and a central layer (26) arranged between the latter. Each outer later is made of palladium and/or a palladium alloy and the central layer is made of niobium and/or tantalum and/or an alloy based on one of said metals. Palladium, niobium and tantalum exhibit high atomic hydrogen diffusibility but are impermeable to larger atoms and molecules. The barrier layer composite separates the anode gas space from the cathode gas space in such a way that the fuel cannot migrate through the electrolyte to the cathode side.

Title: Rechargeable battery electrode testing device
Inventor: WRONSKI ZBIGNIEW S
IPC: G01R31/36
Filed: 2000-12-21
Abstract: A testing device which measures minute changes in battery electrode thickness due to repeated charge/discharge cycles. The testing device uses a moving wall to detect changes in electrode dimensions, typically thickness. The moving wall is adjacent a surface of the electrode, and is connected a sensor that measures wall displacement induced by electrode dimensional changes. Also included in the testing device is a thermocouple that senses the temperature of the device, allowing the data sampling and processing means to correct for thermal expansion/contraction during operation. The testing device can be used during the battery cycling as it does not interfere with the charge/ discharge/recharge process. The testing device can be used to measure either a single electrode, or a plurality of electrodes assembled into an electrode stack and incorporated either into a test cell or into a working battery.
