Experimental Investigation on the Operating Characteristics of Flat-Plate CLPHP for PEMFC Cooling
Round 1
Reviewer 1 Report
The manuscript titled "Experimental investigation on the operating characteristics of flat-plate CLPHP for PEMFC cooling" proposes a practical solution for heat removal from devices to operate at circa 80 deg C, such as the fuel cells. The manuscript content is average, enclosing the fabrication and characterization of a heat sink with a general purpose, without discussing the specifics of serving the electrical device. I consider the paper may be accepted in the present form. The work is original, the abstract encloses information on the main results, the manuscript is well organized, and conclusions are clearly formulated. References are adequate and all illustrations are necessary.
Author Response
Point 1: English grammar and spell check.
Response: Yes, I have carefully revised the English grammar, wordings, and sentences.
Reviewer 2 Report
The manuscript entitled "Experimental investigation on the operating characteristics of flat-plate CLPHP for PEMFC cooling" is within the scope of the World Electric Vehicle Journal. The authors investigated the influence of filling ratios, vacuum degrees, and inclination angles on the working temperature of PEMFC, heat transfer resistance, and internal relative pressure change of flat-plate CLPHP filled with 5:1 mass ratio binary methanol-deionized water working medium. The manuscript is well written and the results are well explained.
Some minor notes:
- Figure 3. ...at 80 oC and 90 oC
- Figure 4. ...at different vaccum degrees.
- Figures 4 and 6. ...versus temperature... What kind of temperature? Is it heat source temperature? Or working temperature of PEMFC?
- Figure 5. Please check the grammar of the figure description.
- Figure 6. ...at different inclination angles. (Please check it...)
Author Response
Point 1: Figure 3. ...at 80℃ and 90℃.
Response: The original "Figure 3. ...in 80°C and 90°C." has been revised to "Figure 3. ...at 80°C and 90°C."
Point 2: Figure 4. ...at different vacuum degrees.
Response: I have modified " Figure 4. ...for vacuum degree." in the manuscript to " Figure 4. ...at different vacuum degrees."
Point 3: Figures 4 and 6. ...versus temperature... “What kind of temperature? Is it heat source temperature? Or working temperature of PEMFC?
Response: This temperature is the average value of the inlet and outlet temperatures of the heat source. Since the heat produced by the PEMFC in this manuscript is replaced by the heat source, this temperature can be understood as the working temperature of the PEMFC.
Point 4: Figure 5. Please check the grammar of the figure description.
Response: I have carefully revised the English grammar, wordings, and sentences.
Point 5: Figure 6. ...at different inclination angles. (Please check it...)
Response: The original " Figure 6. ...for inclination angle." has been revised to " Figure 6. ...at different inclination angles."
