Description
Перенапр жение при плотности тока 100 мА/см2 составл ет 0,090-0,100 В В услови х опыта, описанного в приме ре 1.The overvoltage at a current density of 100 mA / cm2 is 0.090-0.100 V. Under the conditions of the experiment described in Example 1.
По предлагаемому способу перенапр жение при выделении водорода электролизом 30%-How растворе КОН при составл ет 0,030-0,060. В. при плотности тока 100 мА/см При катодном выделении водорода на электродах из никел с поверхностным слоем из вьлцелоченного сплава никел с алюминием плотностью тока 100 мА/см реализуетс при перенапр жении 0,090-0,095 В в 30%-ный раствор КОН при 70 С. Величина перенапр жени снижаетс в 1,5-3 раза, что соответствует увеличению плотности тока при одинаковом значении перенапр жени в 3-6 раз. Это Означает, что при тех же rabapHTak и расходе электроэнергии можно увеличить производипо водотельность электролизера роду в несколько раз.According to the proposed method, the overpotential in the evolution of hydrogen by electrolysis of a 30% -How KOH solution at is 0.030-0.060. V. at a current density of 100 mA / cm With cathode evolution of hydrogen on nickel electrodes with a surface layer of whitened nickel alloy with aluminum, a current density of 100 mA / cm is realized at an overvoltage of 0.090-0.095 V in a 30% KOH solution at 70 ° C The magnitude of the overvoltage is reduced by 1.5-3 times, which corresponds to an increase in the current density at the same value of overvoltage by 3-6 times. This means that with the same rabapHTak and power consumption it is possible to increase the production capacity of the cell electrolyzer several times.
