Abstract
An electrochemical cell comprising a gas electrode, including a deposited layer, and a counter electrode. The gas electrode is an electrode that either utilizes a gas as the active material that is reduced by the gas electrode or produces a gas by oxidation at the gas electrode. In a preferred embodiment, the gas electrode is a thin film electrode including a deposited current collector and deposited active material oxidation or reduction layer. A control layer can be disposed between the gas electrode and the counter electrode to control the diffusion of electrolyte into the gas electrode. Methods for making electrochemical cells having gas electrodes are disclosed.
