The invention relates to an electrode for an electrochemical gas sensor and a manufacturing method and application thereof. The invention relates to an electrode (100) for an electrochemical gas sensor (1), the electrode having a gas-permeable membrane, and a graphene layer (3) applied as electrode material to the gas-permeable membrane (4). Such an electrode (1) is manufactured, for example, by applying a dispersion onto a gas permeable membrane, where the dispersion consists of graphene or graphene oxide in a volatile liquid, and vaporizing the volatile liquid. 用于电化学气体传感器的电极及其制造方法和应用。本发明涉及用于电化学气体传感器（1）的电极（100），其中所述电极具有气体可渗透的膜，并且其中石墨烯层（3）作为电极材料涂敷在气体可渗透的膜（4）上。这样的电极（1）例如通过以下方式来制造：将分散体施加到气体可渗透的膜上，其中所述分散体由在挥发性液体中的石墨烯或者氧化石墨烯组成，并且使所述挥发性液体蒸发。
