Priestnall et al. (2002) proposed a new concept of MR fuel cells called compact mixed-reactant (CMR) fuel cells, based on the use of a structure containing porous flow-though electrodes. Such a structure can be a single cell or stacks of cells connected in series or parallel. In their initial proof-of-principle experiments, the authors used an alkaline fuel cell system with an electrolyte 0.008 M NBH4 in 10 M KOH saturated with air. 

Sealing means must be provided at the edges of the cells to prevent reactants from escaping to the atmosphere from porous elements of the electrodes. Also, since reactant manifolding is usually internal to the stack in small fuel cells (for the sake of compactness), sealing around manifold holes is required to prevent the mixing of reactants between manifolds and electrodes the considerations are the same for internal tie-bolt holes.
