Hot Products

Small PEM hydrogen production electrolyzer
Small PEM hydrogen production electrolyzer
Cawolo independently developed the sealing structure to ensure the excellent airtight performance of the electrolyzer/independently developed the water flow field design, to ensure the high performance of the membrane electrode of the electrolyzer/independently designed the diffusion layer of the cell, to improve the electrolytic performance of the electrolyzer/excellent product performance, with small volume, long service life, high hydrogen production and low attenuation/hydrogen output, and the hydrogen output pressure can be customized as required.
C-CELL desktop hydrogen production and hydrogenation integrated machine
C-CELL desktop hydrogen production and hydrogenation integrated machine
Specifically designed for micro hydrogen production needs of less than 0.5 standard cubic metres, the Xiyuan series hydrogen production equipment is ideal for hydrogen powered vehicles and laboratory hydrogen generators due to its compactness, flexibility and energy efficiency. The pure hydrogen output will help you easily start a new chapter of hydrogen energy application.
Modular hydrogen production system
Modular hydrogen production system
Cawolo modular hydrogen production system adopts the integrated design of hydrogen production, pure water and gas purification, which reduces external pipelines and interfaces, makes the system more compact, has lower failure rate, is easier to maintain/supports modular parallel stacking, and the hydrogen production rate can be linearly increased as required (from 0.5 nm/h to multi-module combination), easily matching different needs from small-scale demonstration to large-scale operation/based on the integrated PEM hydrogen production system, The intelligent filling module is flexibly matched, and the "manufacturing-filling" integrated solution can be quickly constructed to meet the terminal hydrogen charging demand. The number of hydrogen charging channels can be flexibly designed according to the specifications and operation rhythm of solid hydrogen storage bottles, and it is suitable for all kinds of scenes from single bottle filling to multi-bottle parallel/built-in high-efficienc
C-Node

C-Node

C-Node is a modular, plug-and-play green hydrogen generation & charging device.
Specifically designed for solid-state hydrogen storage bottles, it can be easily deployed in distributed scenarios such as scenic spots and industrial parks, providing a safe and convenient solution for small & medium-scale hydrogen energy applications.
Household systems

Household systems

Natural energy harvesting and hydrogen energy conversion
The customer is a farmer. His area has abundant sunlight and his roof is equipped with solar power panels. We customized a home system for him to collect light energy and electrolyze water to produce hydrogen, which can be used to generate electricity at night or in winter. .
