Fuel cell and electricity generation method using the same

摘要

Provided is a fuel cell which can obtain a sufficiently high electromotive force even under a low-temperature condition such as room temperature without using a deleterious substance or platinum. This fuel cell uses an electrolyte layer containing a layer-shaped metal oxide which has been subjected to the steam treatment.

主权项

1. An anion exchange-type fuel cell, comprising:
an electrolyte layer that has oxygen vacancies hydrated with water molecules, the electrolyte layer containing at least one layered metal oxide selected from the group consisting of NaCo2O4 and LaFe3Sr3O10, wherein an ion conductor of the fuel cell is a hydroxide ion (OH—), and wherein the layered metal oxide includes OH groups, which dissociate in the layered metal oxide at higher than 200 degrees Celsius.
