PROBLEM TO BE SOLVED: To provide an evaporator for fuel cell advantageous in modification reaction and stabilization of power generation by achieving stable evaporation in an evaporation chamber.SOLUTION: The evaporator 200 includes a box 300 with an evaporation chamber 301 and a filler 503 with an evaporation accelerator 500 formed with a plurality of spherical ceramics as base material. The box 300 includes a bottom wall 331, a side wall 332, and a corner angle wall 333 crossing the bottom wall 331 and the side wall 332. A curvature radius of an inner wall surface 333i facing the evaporation chamber 301 of the corner angle wall 333 and that of the evaporation accelerator 500 are defined as R1 and R2, respectively. R1 is set to be larger than R2 (R1>R2).

The invention relates to a heat exchanger plate for an evaporator; with a longitudinal axis and a transverse axis, with the transverse axis being disposed perpendicularly or substantially perpendicularly to the longitudinal axis; with at least one flow channel which extends in the direction of the longitudinal axis of the heat exchanger plate through a heat supply area of the heat exchanger plate and conducts the medium to be evaporated; with an inlet for the medium to be evaporated, which inlet is in a flow-conducting connection with the at least one flow channel arranged in the direction of the longitudinal axis of the heat exchanger plate, with a meandering inflow channel being provided in the direction of the longitudinal axis between the inlet and the at least one flow channel arranged in the direction of the longitudinal axis, which inflow channel is in a flow-conducting connection with the inlet and the at least one flow channel, and conducts the medium which flows out of the inlet to the at least one flow channel in an alternating manner along the transverse axis in the direction of the at least one flow channel. The invention is characterized in that the meandering inflow channel is formed by a plurality of webs which are disposed on the heat exchanger plate or a base plate which forms the bottom or top of the inflow channel and the at least one flow channel arranged in the direction of the longitudinal axis, which webs extend in the direction of the transverse axis, and the inflow channel between the webs is subdivided into individual partial channels by a plurality of plates which extend in the direction of the transverse axis.
摘要:
The present invention provides an alkali metal salt of fluorosulfonyl imide having favorable heat resistance and a reduced content of specific impurities and a water content, and provides a method for producing an alkali metal salt of fluorosulfonyl imide, which is capable of easily removing a solvent from a reaction solution. An alkali metal salt of fluorosulfonyl imide of the present invention is represented by the following general formula (I) and has a mass loss rate of 2% or less when the alkali metal salt of fuluorosulufonyl imide is kept at 100°C for 8 hours under an air current. A method for producing an alkali metal salt of fluorosulfonyl imide of the present invention comprises a step of concentrating a solution of the alkali metal salt of fulorosulfonyl imide by bubbling a gas into a reaction solution containing the alkali metal salt of fulorosulfonyl imide, and/or concentrating a solution of the alkali metal salt of fulorosulfonyl imide by thin layer distillation.
