=== Assistant: 以下以理論極限(Faraday 定律、100% 電流效率、忽略所有損耗)來分析,讓你清楚知道「上限在哪裡」。實務值一定只會更低。 === 以下以'''理論極限(Faraday 定律、100% 電流效率、忽略所有損耗)'''來分析,讓你清楚知道「上限在哪裡」。實務值一定只會更低。 ==== - 市電:台灣常見 AC 110 V ==== * 電線承載上限:15 A * 電解方式:水電解產生 H₂ + O₂ * 僅計算 純氫(H₂) * 假設: - 已整流為 DC - 電流全部有效用於電解(100% Faradaic efficiency) - 不考慮過電位、熱損、整流損耗 - 氣體體積以 STP(0°C, 1 atm) 計算 ==== ### ==== 2H2O+2e−→H2+2OH−2H_2O + 2e^- \rightarrow H_2 + 2OH^-2H2O+2e−→H2+2OH− → 產生 1 mol H₂ 需要 2 mol 電子 ===== F=96,485 C/mol e⁻F = 96{,}485 \text{ C/mol e⁻}F=96,485 C/mol e⁻ ===== ==== ### ==== I=15 A=15 C/sI = 15 \text{ A} = 15 \text{ C/s}I=15 A=15 C/s ===== 1596,485=1.55×10−4 mol e⁻/s\frac{15}{96{,}485} = 1.55 \times 10^{-4} \text{ mol e⁻/s}96,48515=1.55×10−4 mol e⁻/s ===== ===== 1.55×10−42=7.78×10−5 mol H₂/s\frac{1.55 \times 10^{-4}}{2} ===== = 7.78 \times 10^{-5} \text{ mol H₂/s}21.55×10−4=7.78×10−5 mol H₂/s ==== ### ==== 1 mol 氣體=22.414 L1 \text{ mol 氣體} = 22.414 \text{ L}1 mol 氣體=22.414 L ===== 7.78×10−5×60=4.67×10−3 mol/min7.78 \times 10^{-5} \times 60 ===== = 4.67 \times 10^{-3} \text{ mol/min}7.78×10−5×60=4.67×10−3 mol/min ===== 4.67×10−3×22.414=0.105 L/min4.67 \times 10^{-3} \times 22.414 ===== = 0.105 \text{ L/min}4.67×10−3×22.414=0.105 L/min ==== : ==== ==== 實務上還要扣掉: ==== * AC → DC 整流損耗(5–15%) * 電極過電位 * 電解液內阻 * 氣泡遮蔽效應 * 電流效率(通常 70–90%) 👉 實際常見值大約只有理論值的 50–70% 也就是: : ==== 若你看到市電 110V / 15A 的設備宣稱: ==== * 1 L/min 氫氣 * 2–3 L/min 氫氧氣 * HHO 可顯著提升能量密度 👉 那在「電化學守恆」下,一定存在誇大或測量條件不透明的問題 ==== - 反推:要 1 L/min 氫氣,理論需要多少電流? ==== * 分析 氫氧混合氣 vs 純氫 的帳怎麼算 * 評估坊間 HHO 車用、鍋爐輔助、燃燒促進 的能量平衡是否合理 * 以你實際應用(引擎?鍋爐?實驗?)做工程等級的可行性分析 你可以直接說用途,我用工程角度幫你拆穿或驗證。
