摘要:
A substrate 10 that selectively allows hydrogen to permeate therethrough is formed with a catalyst thin layer 20 on a first side 11 thereof and is heated in a furnace tube 110, which functions as a reactor, of a heating furnace 100 while a raw material gas to the catalyst thin layer 20 is fed. Hydrogen produced on the first side 11 of the substrate 10 as a result of the formation of carbon nanotubes 5 is separated from the raw material gas and is allowed to permeate to a second side 12 thereof.

摘要:
A tubular fuel cell module is provided with a tubular cell of a tubular fuel cell, and a heat transfer pipe through which a heating/cooling medium flows to selectively heat and cool the tubular fuel cell. The heat transfer pipe includes a first straight portion, a second straight portion, and a bent portion that connects the first straight portion with the second straight portion. At least a portion of the tubular cell is arranged on at least one of the first straight portion and the second straight portion. As a result, the reliability of a seal of the tubular fuel cell module is improved.
