摘要： An electrochemical element (Q) has a metal substrate (1) and multiple electrochemical reaction portions. The metal substrate (1) has gas flow allowing regions that allow the flowing of a gas between the upper side (4) and the lower side (5) of the metal substrate (1). The electrochemical reaction portions each have at least an electrode layer (A), an electrolyte layer (B), and a counter electrode layer (C), and are arranged on the upper side (4) of the metal substrate (1). The electrolyte layer (B) is arranged between the electrode layer (A) and the counter electrode layer (C), and the gas flowing through the gas flow allowing regions is supplied to the electrode layer (A).

摘要： Disclosed are air electrode materials suitable for use in solid oxide electrochemical cells (SOCs). The disclosed cells can operate in a dual function modes, i.e., as a fuel cell and as an electrolysis cell. In both cases, chemical energy and electrical energy can be directly convert from one mode to the other; thereby providing a highly efficient energy conversion process that can be used as a sustainable energy source.
