• The world is facing a massive problem regarding the reduction of greenhouse gases emission to the atmosphere allied to the need for new and renewable energy sources. Photocatalytic fuel cells (PFCs) have been proposed as a pathway to reduce the costs of conventional fuel cells (FCs) by designing new and smart semiconductor materials for harvesting solar energy and concomitantly converting chemical energy directly into electricity with zero carbon emissions. A PFC combines two well-defined approaches for clean energy production and fuel generation, the FCs and photoelectrochemical (PEC) systems. Regardless of being new, the PFC community is growing fast, with several papers published and patents required in the literature in the last years. We present herein a tutorial review containing the most important definitions, working principles, theoretical fundaments, and hands-on on building devices and testing half-cell reactions and performance of PFCs. In addition, for the first time, we review the recent developments of batch and microfluidic PFCs, highlighting and critically discussing the pros and cons of each approach for solar energy conversion into electricity and environmental remediation. [Display omitted] •Review of the most recent advances of batch and microfluidic PFC.•Discussion of working principles, basic fundaments, and mechanisms of PFC.•Tutorial for building PFCs and testing half-cell reactions and performance.•Highlighting advantages and disadvantages of batch and microfluidic PFC.•Critical discussion of future development of high-performance PFCs.
