    Abstract: A pulsatile flow generating apparatus includes a liquid container that contains liquid, multiple rotary movement devices that operate by interlocking with each other, and a microchannel that receives liquid from the liquid container. According to the multiple rotary movement device rotate, a pressure difference, which varies periodically, is generated between the liquid container and the microchannel and wave functional pulsatile flows are formed in the microchannel. Precise wave functional pulsatile microflows, which are not easy to achieve with general pumps while having a simple configuration and a simple manufacturing process, by applying the hydraulic head difference of fluid and controlling the rotation of the rotary movement devices based on Fourier cosine series. In particular, not only the period and amplitude of pulsatile flows can be controlled but also various types of pulsatile flows such as square waves and triangular waves can be obtained, and even two types of operation, forwarding type and back-and-forth standing type, are possible.

    Abstract: 고분자 전해질 연료전지의 운전 시 시동 단계에서 공기보다 연료 가스를 먼저 주입하도록 하면, 고분자 전해질 연료전지의 셀 성능 및 전기화학적 표면적 감소 속도를 늦출 수 있고, 시동과 정지가 반복되는 운전에 있어서 전하 전달 저항 증가 속도를 늦출 수 있다. 이는 고분자 전해질 연료전지의 성능 저하를 완화함으로써 결과적으로 내구성을 향상시키는 것이다. 이에 따르면 고분자 전해질 연료전지의 상용화 특히 전기 자동차의 동력원으로의 상용화에 기여할 수 있다.
