| titleOfInvention | Low-grade heat energy driven electrode liquid self-circulation type hydrogen production method |
| abstract | A low-grade heat energy driven electrode liquid self-circulation hydrogen production method belongs to the technical field of new energy, and continuous hydrogen production is realized by taking low-grade heat energy as a driving force and by means of concentration change of a working solution. The method comprises the following steps: firstly, converting low-grade heat energy into chemical potential energy of a working solution by using a low-temperature multi-effect distillation method; then the chemical potential energy is converted into the potential difference between two electrodes of the cell stack based on the reverse electrodialysis principle; then the hydrogen and oxygen are respectively produced on the hydrogen producing electrode and the oxygen producing electrode in the same electrode liquid by reduction reaction or oxidation reaction, thus realizing the production of hydrogen and oxygen. The waste liquid losing part of chemical potential energy is recovered after flowing out of the cell stack, and then the regeneration is realized under the drive of low-grade heat energy. The electrode liquid is self-circulated between the hydrogen-producing electrode liquid cavity and the oxygen-producing electrode liquid cavity at two ends of the cell stack. The low-grade heat energy can be continuously, efficiently and stably converted and utilized; the hydrogen production system does not need to operate at high temperature and high pressure, the number of mechanical moving parts is small, and the capacity configuration is flexible; the single type of electrode liquid is adopted and is in closed circulation with electrolyte, and the operation can be carried out for a long time only by supplying deionized water. |
