Abstract Seawater electroreduction is attractive for future H 2 production and intermittent energy storage, which has been hindered by aggressive Mg 2+ /Ca precipitation at cathodes consequent poor stability. Here we present a vital microscopic bubble/precipitate traffic system (MBPTS) constructing honeycomb-type 3D robust anti-precipitation seawater reduction (SR), massively/uniformly release small-sized bubbles to almost every corner of the cathode repel precipitates without break. Noticeably, optimal with built-in MBPTS not only enables state-of-the-art alkaline SR performance (1000-h stable operation –1 A cm −2 ) but also highly specialized in catalytically splitting natural into greatest ability. Low amounts after prolonged tests under large current densities reflect genuine efficacy our MBPTS. Additionally, flow-type electrolyzer based on stably functions industrially-relevant 500 mA 150 h while unwaveringly sustaining near-100% Faradic efficiency. Note that estimated price (~1.8 US$/kg H2 even cheaper than US Department Energy’s goal (2 ).
