Chem."],"abstract":"<jats:p>The work in this paper incorporated printed circuit board (PCB) technology into micro-direct methanol fuel cells (\u00b5DMFCs) and conjectured and verified the performance degradation factors of PCB current collectors in \u00b5DMFCs by testing different designed configuration \u00b5DMFCs. The experiment results showed that all kinds of PCB coating can benefit from the porous stainless-steel plates covering to a great extent. At the end of 48\u00a0h discharging, \u00b5DMFCs with porous stainless-steel plates between MEA and PCB coating achieved higher performance than those of the direct contacting series. It can be inferred from various types of experimental data that because of stainless-steel porous plate isolating, the impact of corrosion on the surface of the PCB electrode plate was reduced to a certain extent. The corrosion of the electrode plate was slowed down in the \u00b5DMFC discharging as a result of the passivation behavior on the iron surface and a decrease in corrosion current. Consequently, the attenuation of the PCB performance was delayed. The conclusion of this work explores a practical direction to enhance the cost-effectiveness of fuel cells, promoting the large-scale application of DMFCs in the future.<\/jats:p>","DOI":"10.3389\/fchem.2024.1434996","type":"journal-article","created":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T05:07:31Z","timestamp":1723093651000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["An exploration of the solution of direct methanol fuel cell cost effectiveness"],"prefix":"10.3389","volume":"12","author":[{"given":"Tengyi","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiwei","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Changsheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yang","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinsheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhiquan","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,8,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1115\/1.3075863","article-title":"Investigation into cavitation erosion pits","volume":"131","author":"Abouel-Kasem","year":"2009","journal-title":"J.
