  • Patent number: 10979062
    Abstract: This disclosure describes techniques to perform analog signal conditioning (including filtering and amplification) and analog-to-digital conversion (ADC) on a System-in-package (SIP) assembly technology. In particular, the disclosure combines a programmable gain amplifier (PGA), one or more filter circuits, and an ADC circuit onto the same SIP. These devices are coupled together on the SIP using high-accuracy and precise integrated-passive components. The SIP receives an analog signal, amplifies the analog signal with the PGA on the SIP, filters the amplified analog signal with the filter circuit(s) on the SIP, and then performs analog-to-digital conversion on the filtered amplified analog signal with the ADC circuit on the SIP. The SIP can be configured for various applications based on a variety of inputs and control mechanisms.

  • Patent number: 7977005
    Abstract: A fuel cell including an anode-side catalyst coated membrane and a cathode-side catalyst coated membrane. At least a portion of a reduced-permeability layer is disposed between the ionically conductive membrane and the anode-side and cathode-side gas diffusion media, wherein the reduced-permeability layer is formed of a material that has a permeability that is less than a permeability of the ionically conductive member. The reduced-permeability layer may also be formed of a material that is softer than the ionically conductive membrane.

  • Patent number: 7132191
    Abstract: A method of addressing one MEA failure mode by controlling MEA catalyst layer overlap, and the apparatus formed thereby is disclosed. The present invention addresses a feature of membrane electrode assembly (MEA) architecture that is associated with field failures due to the loss of ionomer from the edges of the electrolyte. To address ionomer degradation, the present invention provides a MEA design in which the cathode catalyst edges are closer than the anode catalyst edges to the edges of the electrolyte.

  • Patent number: 6773841
    Abstract: Fuel cell stack having a plurality of liquid-cooled, bipolar plates separating one cell from the next. Coolant inlet and outlet manifolds are defined, in part, by surfaces of the bipolar plates, and respectively supply coolant to, and remove coolant from, the bipolar plates. The surfaces of the bipolar plates that define the coolant manifolds and confront the coolant in the manifolds are coated with a non-conductive coating to reduce shunt current flow through the coolant.
