| Outline of Final Research Achievements |
In power generation of a solid oxide fuel cell which operates at high temperature, the steep increase of the output has a possibility of a damage of its fuel electrode due to a lack of hydrogen gas supplied to the reaction area. The aim of study was to develop measurement techniques of transient change of hydrogen gas concentrations in the both of the channel for the fuel gas and the fuel electrode during the power generation. By measuring the hydrogen gas concentrations at the both positions, the transfer rate of hydrogen gas is obtained, and then it is possible to determine the minimum amount of hydrogen gas supplied to the reaction area.
The hydrogen gas concentration in the channel for the fuel gas could be measured by a laser interferometry, and also that in the electrode could be measured with an oxygen sensor which was made of a platinum wire coated with zirconia.
