    摘要： A particle adhesion device includes: a holder; a chamber; a nozzle; an intake port; and a flow control member. The holder holds a filter substrate having a first end face and a second end face. The chamber is in communication with the holder and is arranged so that the first end face of the filter substrate faces a space in the chamber. The nozzle is arranged on an opposite surface of the chamber opposing to the first end face of the filter substrate, and can inject an aerosol containing particles toward the first end face of the filter substrate. The intake port is provided on the opposite surface of the chamber and can incorporate an ambient gas. The flow control member is arranged on the opposite surface provided with the intake port, and can control the flow of the ambient gas.

    摘要： An electrochemical cell includes: a metal substrate having a principal surface and a plurality of connecting holes formed in the principal surface; and a cell body disposed on the principal surface. The cell body has: a gas diffusion layer disposed on the principal surface, the gas diffusion layer being electrically conductive; a first electrode layer disposed on the gas diffusion layer; a second electrode layer; and an electrolyte layer disposed between the first electrode layer and the second electrode layer. The metal substrate has: a gas-permeable region in which the plurality of connecting holes are formed; and a non-gas-permeable region surrounding the gas-permeable region in a plan view. The gas diffusion layer has: a first region formed on the gas-permeable region; and a second region formed on the non-gas-permeable region. The second region has a crack-preventing space in a cross section along a thickness direction.
