  • Patent number: 10882744
    Abstract: An apparatus and method for purifying a raw hydrogen gas stream of chloramines and chlorine is provided. The explosive chloramines compounds can be effectively captured by the carbon adsorbent without accumulating on the carbon surface. Rather, the chloramines are converted via decomposition, into non-explosive products with catalytic effect of the carbon material. Chlorine reacts with impregnated reducing agent on the carbon surface to form the solid products, which can be adsorbed on the carbon surface. The purified hydrogen gas contains little to no trace of chloramines and chlorine impurities, thereby making the hydrogen gas suitable for liquid hydrogen production.

  • Patent number: 10503578
    Abstract: An on-chip TDDB degradation monitoring and failure early warning circuit for SoC. A control circuit module converts Q1 and Q0 signals into a switch state control signal and outputs the switch state control signal to a digital conversion module for TDDB performance degradation. A MOS transistor of a first MOS transistor circuit within the digital conversion module for TDDB performance degradation is in a stress state of a supply voltage, and a MOS transistor of a second MOS transistor circuit is in a non-stress state. The first and second MOS transistor circuits output a first frequency value and a second frequency value to the output selection module. The output selection module outputs the first frequency value from the digital conversion module to the counter B for recording, or outputs the second frequency value to the counter A for recording. The counter module determines the degradation level of TDDB performance.
