摘要：
A hydrogen sensor includes a support having a first temperature sensor, a heating element and an evaluation unit. The hydrogen sensor furthermore includes a mass flow reduction apparatus by which a gas mass flow over the first temperature sensor and the heating element is reduced. The evaluation unit determines a hydrogen concentration in a gas or gas mixture based on a first temperature detected by the first temperature sensor. A detection method for hydrogen concentration having the hydrogen sensor and a motor vehicle having a fuel cell drive having the hydrogen sensor.
