1. Introduction
Thank you for purchasing our Compact SOFC Test Holder with furnace.
This holder employs entirely ceramic structure to be free from metallic contamination. In addition,
since the load structure of the ceramic spring is realized with a compact design, the cell can be durably
tested in a space-saving manner.
To understand the product and prevent any trouble occurrence read this instruction manual before
operation. This instruction manual describes notes when using, building and maintenance.
・Make sure to maintain exhaust gas roots so as using flammability gas like H2.
→There might be a danger of ignition or poisoning.
・Purging by inert gas like N2before and after the testing. There might be danger of ignition and
fire.
・Do not close flammable substances to the furnace during operation of the furnace.
→ There might be danger of fire. Take enough time to make the furnace cool down.
・Be careful handling the Holder, which is made of ceramics only.
・Holder should be installed not to apply load to the exhausting tube as possible. Handling the
Holder, it allows only grasping the body not tubes.
→ It may cause damage to the Holder.
・This Holder is not a structure of proof against pressure. Please keep the vent open (pressure to
be zero) when
inject gas to the Holder due to burst and failure.
・It not allows setting the values more over:
heat up speed (max. 5 ºC/min), gas flow (max. 1L/min), current (max. 10 A).

３．ホルダの組立方法
The bellow describes how to build a holder.
①When you unpack, firstly make sure lead wires are inserted in groove of diffusion plate. (Both side anode
and cathode)
②Place gas seal to the holder flame. It is recommended that gas seal is 2 places with adhesive. (both side
anode and cathode)
③Place anode current collector to set on inside of gas seal. (φ12, t = 0.6）
④Put quick adhesive for temporary adhesion to the gas seal of the anode side. Put to position cell and seal
edge.

⑤Place cathode current collector (40 x 40, t = 0.6) on the seal position of cathode side holder.
⑥Set cathode side holder in alumina fixture chest. Stack anode side holder on the cathode side holder
after checking that the cell doesn’t fall the anode side. Insert ceramic spring to the counterbore of anode
side holder and set alumina fixture lid on the ceramic spring. Insert ceramic clincher to the hole of the
lid and tighten with a hex driver. Then, tighten each clincher little by little so that the gap between the
container and the lid becomes uniform.
※Since wear of clincher can be reduced, it is recommended to apply grease to crests of ceramic threads.

４．Location in the furnace
The below describes how to locate the holder in the furnace
Position the holder so that the depth is the mark of almina piping overlaps the outside of the insulating
block, and center in the left-right direction.Adjust the height of the holder with setters.
Insert the insulation block, tighten the fixture, heat the insulation block by filling the gap with the
insulation material.
※It isrecommended touseaflexibletubeto reducetheload onthegasintroductionpipeforconnectiontopiping.
After wiring and tube connecting, heat furnace in a speed within 5 ºC/min.

５．How to change lead wire
Lead wires might have deteriorated after repeated testing.
Replace lead wire if deteriorated state be founded.
①Start work with the cell, gas seal, current collector removed.
②Removeairtightterminalfrommetalfitting.Atthistime,remove the airtightterminalwhilepushingthepinofthephoto
○part. Pull outslowlywhilepushingthe tipof theleadwireinthe mainbodyholderwithtweezersor the like.
③Fuse the solder part of the airtight terminal and pull out the used wiring.
④Cover by insulation tube not to conduct between connector and wires , let new wires into sealing
terminal.
⑤Soldernewwiresletintosealingterminal.
