Abstract:
Provided is a hydrogen refining pressure-boosting device which is durable even in a high-pressure environment. This hydrogen refining pressure-boosting device produces, from a hydrogen-containing gas, a refined hydrogen gas having higher pressure and higher purity than the hydrogen-containing gas. The hydrogen refining pressure-boosting device is equipped with multiple stacked cell structures, and a pressing structure that applies tightening stress in the direction in which the cell structures are stacked. In this hydrogen refining pressure-boosting device the flow path surface of a cathode-side separator is sized so as to be contained on the inside of the flow path surface of an anode-side separator, in the direction of a plane parallel to a solid polymer electrolyte membrane.

The hydrophilic unit has divalent hydrophilic groups composed of one aromatic ring or a plurality of aromatic rings, at least one of which has an anion exchange group, that are repeated via carbon-carbon bond. The divalent fluorine-containing groups have a specific structure and are bonded via carbon-carbon bond to the hydrophobic unit and/or the hydrophilic unit and/or a moiety other than these units.
Abstract:
A blood purifier comprises hollow fiber membranes allowing a dialysing fluid or a filtrated fluid to flow outside. The membrane has an effective length of 10 mm or more and 150 mm or less. A maximum value of a permeation flux Jv obtained by dividing a volume of a permeate fluid permeating through the membranes by a membrane area of the hollow fiber membranes and time, is represented as Jvmax. A linear velocity of blood flowing in the membrane is represented as uB. A pressure difference between blood flowing inside the membranes and a fluid flowing outside the membranes is represented as TMP. When a filling blood volume into the membranes per unit membrane area is 20 mL/m2 or more and 35 mL/m2 or less and Jvmax/uB has a value of 0.00015 or more and 0.0006 or less, a TMP change rate is 0.95 or more and 1.05 or less.
