  • Patent number: 10809170
    Abstract: A dynamic mechanical analysis system provides an actuator that imparts expansion and contraction forces (e.g. shear force) to a viscoelastic material at high frequencies. Such high frequency analysis allows for the direct and accurate measurement of the characteristics of the material at high expansion/contraction frequencies directly, without the use of additional predictive analysis techniques, such as time-temperature superposition. The system also utilizes a clamping system, whereby two different sections of the viscoelastic material are held in place between by a pair of fixed clamps and a force member that is moved by the actuator. As such, the system is able to subject the viscoelastic material sample to simulated “road” conditions to identify various performance properties associated with the material sample.
    Type: Grant

  • Patent number: 10788445
    Abstract: A polymer electrolyte membrane fuel cell (PEMFC) sensor includes an anode and a cathode with a polymer electrolyte disposed therebetween. The anode and cathode are configured with asymmetric catalyst loadings, such that the catalyst loading on the cathode is lower than that of the anode. Accordingly, due to the reduction of the amount of catalyst utilized, the cost of fabricating the sensor is substantially reduced.
