AbstractPurpose -The aim of this article is to examine the differences in service quality between public and private hospitals in Turkey. Design/methodology/approach -This study applies the principles behind the SERVQUAL model and compares Turkey's public and private hospital care service quality. The study sample contains a total of 200 outpatients. Through the identification of 40 service quality indicators and the use of a Likert-type scale, two questionnaires containing 80-items was developed. The former measured patients' expectations prior to admission to public and private hospital service quality. The latter measured patient perceptions of provided service quality. Findings -The results indicate that inpatients in the private hospitals were more satisfied with service quality than those in the public hospitals. The results also suggest that inpatients in the private hospitals were more satisfied with doctors, nurses and supportive services than their counterparts in the public hospitals. Finally, the results show that satisfaction with doctors and reasonable costs is the biggest determinants of service quality in the public hospitals. Originality/value -Consequently, SERVQUAL, as a standard instrument for measuring functional service quality, is reliable and valid in a hospital environment.

This study presents a more efficient and innovative prototype of a hydrogen generation system using proton exchange membrane (PEM) electrolyzer. The aim of this study is to generate hydrogen gas energy that conducts the chemical reaction by electrolytic movements as well as to design a system that generates energy with H2 through new technology. The Cr‐C coated SS304 bipolar plates were used in the electrolysis cells and the septic mixture (urea, ammonia, methyl alcohol) was used in the electrolyzer as a chemical solution to make the hydrogen production more efficient and cost effective. The super strong magnets were also mounted on the outer surface of the electrolysis cells to improve the performance and efficiency. The performance of the electrolyzer was determined by operating the current and voltage parameters. The results were collected through experiments and the optimization of the different parameters. In this prototype study, the production of hydrogen gas in the system (1 MW) through the presented system was found to be as 6 m3 h−1 and the simple payback period (SPP) was calculated as 2.32 y. These results indicate that this system can produce hydrogen more efficiently and economically.
